Persistent unexplained fatigue, unintended weight loss, a lump that does not go away, or blood where it should not be — these are among the most common early warning signs of cancer that should never be dismissed or attributed to ageing alone. Cancer is a condition in which abnormal cells divide uncontrollably and can invade or spread to other tissues and organs — and with over 14 lakh new cases diagnosed in India every year, cancer marker testing and early screening are among the most critical services available at a medical laboratory. healthcare nt sickcare in Aundh, Pune offers comprehensive cancer blood tests with home sample collection and direct walk-in facility — making early cancer detection accessible and affordable across Pune and Maharashtra.

What Is Cancer? Definition and How It Develops
Cancer is not a single disease — it is a group of more than 100 distinct diseases, all characterised by the uncontrolled growth and division of abnormal cells that invade surrounding tissue and may spread (metastasise) to distant organs via the bloodstream or lymphatic system.
Micro-definition: Cancer develops when the normal biological mechanisms that regulate cell division and cell death (apoptosis) are disrupted by genetic mutations — either inherited, acquired through carcinogen exposure, or caused by chronic infection or inflammation. The World Health Organisation identifies cancer as one of the leading causes of death globally, responsible for nearly 10 million deaths annually — with early detection and treatment being the single most effective strategy for reducing cancer mortality.
Cancer Types: Major Categories and Common Cancers in India
Cancer is classified based on the type of cell or tissue from which it originates — with each cancer type having distinct symptoms, staging criteria, and treatment protocols.
Most Common Cancer Types in India
| Cancer Type | Primary Site | Most Common In | Key Tumour Marker |
|---|---|---|---|
| Breast cancer | Breast ducts / lobules | Women (most common cancer in Indian women) | CA 15-3, CEA, IHC panel (ER/PR/HER2) |
| Cervical cancer | Cervix | Women (2nd most common in India) | Pap smear, HPV DNA, SCC antigen |
| Oral / head-neck cancer | Mouth, throat, larynx | Men (tobacco-related; high in India) | SCC antigen, CEA, CYFRA 21-1 |
| Lung cancer | Lung tissue | Smokers; leading cancer death cause globally | CYFRA 21-1, CEA, NSE |
| Prostate cancer | Prostate gland | Men above 50 | PSA, Free PSA |
| Ovarian cancer | Ovaries | Women; often called "silent killer" | CA-125, HE4 |
| Colorectal cancer | Colon / rectum | Adults above 45 | CEA, CA 19-9 |
| Blood cancer (leukaemia / lymphoma) | Blood, bone marrow, lymph nodes | All ages; can affect children | CBC with differential, LDH, Beta-2 microglobulin |
| Stomach / gastric cancer | Stomach lining | Adults; H. pylori infection a key risk | CEA, CA 72-4, CA 19-9 |
| Liver cancer | Liver cells (hepatocytes) | Hepatitis B/C patients; alcohol-related | AFP (Alpha-fetoprotein) |

Cancer Stages: Understanding How Cancer Is Classified
Cancer staging describes how far a cancer has developed or spread — and directly determines the most appropriate treatment, the likelihood of cure, and the overall prognosis.
Micro-definition: Cancer staging uses the TNM system — where T (Tumour) describes the size and invasion depth of the primary tumour, N (Nodes) indicates whether regional lymph nodes are involved, and M (Metastasis) records whether the cancer has spread to distant organs. Stages are numbered 0 through IV — Stage 0 being pre-invasive (carcinoma in situ) and Stage IV indicating distant metastasis.
Breast Cancer Stages
- Stage 0 — Ductal carcinoma in situ (DCIS): abnormal cells confined to milk ducts; non-invasive; highly treatable
- Stage I — Small tumour (≤2 cm), no lymph node involvement; surgical cure rates exceed 95%
- Stage II — Larger tumour (2–5 cm) or limited lymph node spread; surgery plus adjuvant therapy standard
- Stage III — Locally advanced; spread to chest wall, skin, or multiple lymph nodes; requires multimodal treatment
- Stage IV — Metastatic breast cancer: spread to lungs, liver, bones, or brain; treatable but not curable; focus on quality of life
Key lab test: IHC Panel for Breast Cancer (ER, PR, HER2/neu receptor status) — essential for targeted therapy selection at any stage. The CA 15-3 test monitors treatment response and recurrence.
Prostate Cancer Stages
- Stage I — Cancer confined to prostate; very small and slow-growing; detected incidentally or via PSA screening; active surveillance often appropriate
- Stage II — Still prostate-confined but larger or more aggressive (higher Gleason score); surgery or radiation curative
- Stage III — Spread beyond prostate capsule to seminal vesicles or bladder neck; hormone therapy added to local treatment
- Stage IV — Distant metastasis (typically to bones, lymph nodes, liver); hormone therapy, chemotherapy, or immunotherapy used
Key lab tests: PSA (Prostate Specific Antigen) for initial screening and monitoring; Free PSA test helps distinguish benign prostatic hyperplasia from malignancy. Both available at healthcare nt sickcare with home collection.
Cervical Cancer Stages
- Stage I — Confined to cervix; sub-divided by depth of invasion; surgical cure rate above 90% at Stage IA
- Stage II — Spread beyond cervix to upper vagina or parametrium; combined radiation and chemotherapy standard
- Stage III — Spread to lower vagina, pelvic wall, or causing kidney obstruction (hydronephrosis)
- Stage IV — Invasion of bladder or rectum (IVA), or distant metastasis to lungs or liver (IVB)
Key screening tests: Conventional Pap Smear and the more sensitive Liquid-Based Cytology (LBC) Pap Smear — both performed at the Aundh walk-in centre.
Causes of Cancer: Why Do Normal Cells Become Cancerous?
Cancer arises when genetic mutations disrupt the normal mechanisms controlling cell growth, division, and programmed cell death — with most cancers resulting from a combination of inherited predisposition, environmental exposure, and lifestyle factors.
- Tobacco use — The single largest preventable cause of cancer in India, responsible for oral, lung, stomach, bladder, kidney, and oesophageal cancers; all forms of tobacco — cigarettes, bidis, gutka, and smokeless tobacco — are carcinogenic
- Chronic infections — HPV causes 99.7% of cervical cancers; hepatitis B and C viruses cause liver cancer; H. pylori causes stomach cancer; EBV causes certain lymphomas. These infections are detectable by laboratory testing.
- UV and radiation exposure — Prolonged sun exposure without protection causes skin cancer (basal cell carcinoma, squamous cell carcinoma, and melanoma)
- Diet and obesity — Diets high in red and processed meat, low in fibre, fruits, and vegetables increase colorectal cancer risk; obesity is linked to breast, endometrial, and colorectal cancers through excess oestrogen and insulin signalling
- Alcohol consumption — Causally linked to cancers of the mouth, throat, oesophagus, liver, breast, and colorectum; risk increases dose-dependently with consumption
- Inherited genetic mutations — BRCA1/BRCA2 mutations increase lifetime breast and ovarian cancer risk to 45–85%; Lynch syndrome increases colorectal, endometrial, and ovarian cancer risk; familial adenomatous polyposis (FAP) causes nearly certain colorectal cancer without intervention
- Occupational carcinogens — Asbestos (mesothelioma, lung cancer), benzene (leukaemia), formaldehyde (nasopharyngeal cancer), and aflatoxin (liver cancer) are known industrial carcinogens
- Age — The risk of most solid tumours increases with age as DNA damage accumulates and immune surveillance declines; most cancers in India are diagnosed after age 40
Early Symptoms and Warning Signs of Cancer
Unexplained weight loss of more than 5 kg without dietary change or increased activity is one of the most consistent early warning signs across multiple cancer types — including stomach, lung, liver, and blood cancers.
The following symptoms warrant prompt medical evaluation — especially when persistent for more than 2–3 weeks without an obvious explanation:
- Persistent unexplained fatigue — Not relieved by rest; a hallmark of blood cancers and cancers involving bone marrow
- Unexplained weight loss — Loss of 5–10% body weight without trying; common in stomach, pancreatic, oesophageal, and lung cancers
- A lump or thickening — In the breast, neck, armpit, or groin that is new, firm, or growing
- Abnormal bleeding — Blood in urine (haematuria) suggests bladder or kidney cancer; rectal bleeding suggests colorectal cancer; abnormal vaginal bleeding suggests cervical or endometrial cancer; coughing up blood suggests lung cancer
- Persistent pain — Bone pain suggests bone cancer or metastasis; abdominal pain suggests pancreatic, stomach, or ovarian cancer; headaches with vision changes suggest brain tumour
- Skin changes — New or changing moles (ABCDE rule: Asymmetry, Border irregularity, Colour variation, Diameter >6 mm, Evolution); yellowing of skin and eyes (jaundice) suggests liver involvement; non-healing sores
- Changes in bowel or bladder habits — Persistent constipation, diarrhoea, or narrowing of stools lasting more than 4 weeks; frequent or painful urination with haematuria
- Difficulty swallowing or persistent hoarseness — Suggests oesophageal, throat, or lung involvement
- Night sweats or persistent fever without infection — Classic symptoms of lymphoma and leukaemia
How to Test for Cancer? Cancer Marker Tests Explained
Cancer marker tests (also called tumour marker tests) are blood tests that measure specific proteins, enzymes, hormones, or genetic material produced by cancer cells or released into the bloodstream in response to cancer — used for screening, diagnosis, staging, treatment monitoring, and recurrence detection.
Micro-definition: A tumour marker is a biological substance — found in blood, urine, or tissue — that is produced by cancer cells or by normal cells in response to cancer. Elevated tumour marker levels alone are rarely sufficient to diagnose cancer; they are used in combination with imaging (ultrasound, CT, MRI) and tissue biopsy for a definitive diagnosis. However, they are highly valuable for monitoring treatment response and detecting recurrence in known cancer patients.

The Tumour Panel Test (Female) and Tumour Panel Test (Male) offer broader multi-marker panels for comprehensive screening. Explore all cancer tests and packages at healthcare nt sickcare.
Does a CBC Test Detect Cancer?
A Complete Blood Count (CBC) cannot diagnose cancer directly — but abnormal CBC results are often the first laboratory indicator prompting further investigation for blood cancers, bone marrow disorders, and other malignancies.
Specific CBC findings that may suggest cancer include: very high or very low white blood cell count (possible leukaemia or lymphoma), unexplained severe anaemia (possible bone marrow involvement, colorectal cancer, or blood cancer), very low platelet count (thrombocytopenia — suggesting bone marrow suppression), and high ESR with anaemia (classic in multiple myeloma). The Complete Blood Count (Haemogram) at healthcare nt sickcare is the starting point for cancer investigation, available with home collection. Read our dedicated article on how to test for blood cancer for detailed blood cancer screening information.

Cancer Risk Factors: What Increases Your Risk?
Understanding cancer risk factors does not mean cancer is inevitable — but it guides the frequency and type of screening tests needed, and highlights lifestyle changes that reduce risk most effectively.
- Age above 40 — Risk of most solid tumours rises significantly after 40 in India; annual health checkups including cancer markers become important. See our guide on preventive health screenings by age group.
- Family history — First-degree relative with breast, ovarian, colorectal, or prostate cancer significantly elevates personal risk; start screening 10 years earlier than the affected relative's diagnosis age
- Chronic infections — Hepatitis B/C (liver cancer risk), HPV (cervical cancer), H. pylori (stomach cancer), HIV (lymphoma, Kaposi sarcoma) — all detectable by blood and PCR tests
- Tobacco and alcohol — The two most modifiable and highest-impact risk factors for multiple cancer types in India
- Obesity and metabolic disease — Type 2 diabetes, hyperinsulinaemia, and chronic inflammation associated with obesity all promote tumour growth. See our guide on how to test for diabetes.
- Thyroid disorders — While thyroid cancer is a separate condition, thyroid dysfunction affects hormonal balance relevant to breast and endometrial cancer risk. See our guide on how to test for thyroid disorders.
Cancer Treatment Options: A Brief Overview
Cancer treatment is always individualised based on cancer type, stage, tumour biology (hormone receptors, genetic mutations), patient age, and overall health — with most modern protocols combining two or more of the following approaches.
- Surgery — Removal of the primary tumour; most effective for localised cancers (Stage I–II); may be preceded by neoadjuvant chemotherapy to shrink the tumour first
- Radiation therapy — Targeted high-energy beams destroy cancer cells; used alone or after surgery (adjuvant radiation) for breast, cervical, prostate, head/neck, and brain cancers
- Chemotherapy — Systemic drug treatment that kills rapidly dividing cells; used for advanced cancers, blood cancers, and as adjuvant therapy after surgery
- Targeted therapy — Drugs that specifically block cancer cell signalling pathways (e.g., trastuzumab/Herceptin for HER2-positive breast cancer; imatinib for CML); guided by tumour marker and IHC panel results
- Immunotherapy — Treatments that activate the immune system to recognise and destroy cancer cells; increasingly used in lung, melanoma, and blood cancers
- Hormone therapy — Reduces oestrogen or testosterone that fuels hormone-receptor-positive breast and prostate cancers; guided by IHC panel and hormone assay results
Cancer Prevention: Evidence-Based Precautions
The Indian Council of Medical Research (ICMR) and WHO estimate that approximately 30–50% of all cancers are preventable through lifestyle modification and vaccination alone.
- Eliminate all tobacco use — cigarettes, bidis, gutka, pan masala, and smokeless tobacco
- Limit alcohol — ideally eliminate; no "safe" level of alcohol exists for cancer prevention
- Maintain a healthy body weight through a diet rich in fruits, vegetables, legumes, and whole grains
- Exercise regularly — at least 150 minutes of moderate activity weekly reduces breast, colon, and endometrial cancer risk
- Get vaccinated — HPV vaccine (cervical cancer prevention) and Hepatitis B vaccine (liver cancer prevention)
- Protect skin from UV exposure — use SPF 30+ sunscreen, protective clothing, and avoid peak sun hours
- Undergo age-appropriate screening — annual PSA from age 50 for men, Pap smear every 3 years for women from age 25, CBC annually from age 35
- Perform regular self-examination — monthly breast self-exam for women; skin self-check for mole changes in all adults

People Also Ask About Cancer Tests and Cancer Types
A cancer marker test (tumour marker test) is a blood test that measures specific proteins or substances elevated in the bloodstream in the presence of cancer or certain non-cancerous conditions. Examples include PSA for prostate cancer, CA-125 for ovarian cancer, CEA for colorectal and lung cancers, and CA 15-3 for breast cancer. Accuracy varies by marker and cancer type — PSA screening for prostate cancer is well-validated, while CA-125 has a moderate sensitivity for ovarian cancer. No single tumour marker test can diagnose cancer definitively; a positive or elevated result always requires follow-up with imaging (ultrasound, CT, or MRI) and tissue biopsy for confirmation. Tumour markers are most valuable for monitoring treatment response and detecting recurrence in patients with a known cancer diagnosis. healthcare nt sickcare in Pune offers all major cancer marker tests with home collection and 24–48 hour digital reports.
In India, breast cancer is the most common cancer in women (accounting for approximately 27% of all female cancers), while oral and head-neck cancers are the most common in Indian men due to high tobacco use. Cervical cancer is the second most common cancer in Indian women. Colorectal, lung, stomach, and blood cancers are also among the top 10 cancers in India. Early detection methods vary by cancer type: breast cancer — monthly self-examination, annual clinical breast exam from age 30, and annual mammogram from age 40; cervical cancer — Pap smear every 3 years from age 25, combined with HPV testing; prostate cancer — annual PSA test from age 50 (age 45 for high-risk men); colorectal cancer — colonoscopy from age 45; blood cancers — CBC with differential as the primary screening test. All relevant blood tests are available at healthcare nt sickcare in Pune.
The 7 classic warning signs of cancer — often remembered by the acronym CAUTION — are: Change in bowel or bladder habits (persistent constipation, diarrhoea, or blood in stools or urine); A sore that does not heal; Unusual bleeding or discharge from any body opening; Thickening or a lump in the breast or elsewhere; Indigestion or difficulty swallowing that persists; Obvious change in a wart, mole, or skin growth; Nagging cough, hoarseness, or shortness of breath that persists. Additional warning signs specific to India include unexplained significant weight loss, persistent fever without infection (lymphoma/leukaemia), persistent bone pain (metastasis), and pelvic pain or abnormal vaginal bleeding in women. Any of these symptoms persisting for 2 weeks or more without explanation warrants a blood test panel and medical consultation. Contact healthcare nt sickcare in Pune for cancer screening blood tests with home collection.
For adults in India above age 40, the following cancer-related tests are recommended as part of an annual health checkup: Complete Blood Count (CBC) — screens for blood cancers and anaemia from internal bleeding; PSA test — prostate cancer screening for men above 50 (or 45 for high-risk); CA-125 — ovarian cancer monitoring for women above 40 with risk factors; CEA — colorectal cancer marker, particularly for those with family history; Pap smear — cervical cancer screening for women every 3 years from age 25; CA 15-3 — breast cancer monitoring for those with personal or family history; CYFRA 21-1 — lung cancer marker for current or ex-smokers; and Liver Function Test (LFT) plus AFP if hepatitis B/C positive. healthcare nt sickcare in Pune offers comprehensive cancer marker panels for both men (Cancer Test for Male) and women (Cancer Test for Female / CANFE) with home collection and reports within 48 hours.
Several persistent myths about cervical cancer prevent Indian women from seeking screening. The most common myths and facts are: Myth — "Cervical cancer only affects older women." Fact — it can affect sexually active women of any age from their 20s onwards; early screening from age 25 is essential. Myth — "Pap smear detects all cervical cancer cases." Fact — Pap smear sensitivity is approximately 70–80%; combining it with HPV DNA testing improves detection to over 95%. Myth — "The HPV vaccine is only for young girls." Fact — the vaccine benefits women up to age 26 who are not yet infected with HPV, and in some guidelines up to age 45 for high-risk women. Myth — "Cervical cancer has no symptoms in early stages." Fact — pre-cancerous changes are indeed asymptomatic, which is exactly why regular Pap smear screening is critical — to detect changes before they become invasive cancer. Both the Conventional Pap Smear and the more sensitive Liquid-Based Cytology Pap Smear are available at healthcare nt sickcare's Aundh walk-in centre.
Certain cancers can be strongly suspected — and in some contexts provisionally diagnosed — through blood tests without a biopsy, though tissue biopsy remains the gold standard for a definitive cancer diagnosis. Blood tests that aid cancer detection include: CBC with differential (blood cancers — leukaemia, lymphoma); tumour marker panels (PSA, CA-125, CEA, AFP — raising or lowering cancer suspicion); LDH and Beta-2 microglobulin (lymphoma staging); AFP with liver imaging (hepatocellular carcinoma in hepatitis patients); and comprehensive cancer marker panels (Cancer Test for Male or Female at healthcare nt sickcare). Liquid biopsy — detecting circulating tumour DNA (ctDNA) in the blood — is an emerging technique increasingly used in specialised oncology centres for non-invasive cancer detection and monitoring. For any elevated cancer marker result, healthcare nt sickcare's reports are formatted for direct sharing with an oncologist who will recommend appropriate imaging and biopsy if indicated.
