Introduction
Cancer can affect people of any age, but knowing the warning signs of common cancers can help people seek medical advice at the right time.
According to the latest GLOBOCAN 2024 estimates for India, there were approximately 1.56 million new cancer cases and more than 900,000 cancer deaths in the country in 2024. The five cancers with the highest number of new cases in both sexes combined were breast cancer, lip and oral cavity cancer, lung cancer, colorectal cancer and cervical cancer.
Importantly, the pattern differs between men and women. Lip and oral cavity cancer was the leading cancer among Indian men, while breast cancer was the leading cancer among Indian women in the latest GLOBOCAN estimates.
Recognising a warning sign does not mean you have cancer. Many symptoms can have non-cancerous causes. However, symptoms that are persistent, unexplained, unusual or progressively worsening should be evaluated by a healthcare professional.
In this article, we explain the top 5 most common cancers in India, their warning signs, major risk factors and what you should do if you notice a concerning change.
What Are the 5 Most Common Cancers in India?
Based on the latest GLOBOCAN 2024 estimates, the five leading cancers in India by number of new cases are:
| Rank | Cancer | Estimated New Cases in 2024 | Percentage of All New Cases |
|---|---|---|---|
| 1 | Breast cancer | 237,231 | 15.2% |
| 2 | Lip & oral cavity cancer | 205,878 | 13.2% |
| 3 | Lung cancer | 112,659 | 7.2% |
| 4 | Colorectal cancer | 83,577 | 5.3% |
| 5 | Cervical cancer | 79,360 | 5.1% |

At a Glance: India’s Top 5 Cancers
Important: Cancer rankings can change depending on whether we look at men, women or both sexes combined. The figures above are population-level estimates and should not be interpreted as an individual’s personal cancer risk.
1. Breast Cancer
Why is breast cancer important in India?
Breast cancer is the most common cancer in India overall and the most common cancer among Indian women. GLOBOCAN 2024 estimated approximately 237,231 new breast cancer cases in India. Among women, breast cancer accounted for around 30.4% of estimated new cancer cases.
Breast cancer can also occur in men, although it is much less common.
Warning Signs of Breast Cancer
Watch for:
- A new lump or thickening in the breast
- A lump or swelling in the armpit
- A change in breast size or shape
- Skin dimpling or puckering
- Persistent changes in the nipple
- Nipple turning inward
- Unusual nipple discharge, particularly bloody discharge
- Persistent swelling or skin changes
- Unexplained changes affecting one breast
What Should You Do?
If you notice a new or persistent breast change:
Step 1: Don’t panic or assume it is cancer.
Step 2: Arrange a clinical evaluation.
Step 3: Follow your doctor’s advice regarding imaging such as mammography or ultrasound.
Step 4: If an abnormality requires further evaluation, a biopsy may be recommended.
Early detection matters. IARC identifies breast cancer as one of the common cancers in India where early detection can play an important role in improving outcomes.
2. Lip and Oral Cavity Cancer
Lip and oral cavity cancer is particularly important in India because tobacco use is a major preventable risk factor.
According to GLOBOCAN 2024, approximately 205,878 new cases of lip and oral cavity cancer were estimated in India, making it the second most common cancer overall and the leading cancer among Indian men.
Warning Signs of Oral Cancer
Do not ignore:
- A mouth ulcer that does not heal
- A persistent white or red patch
- A lump or thickening inside the mouth
- Persistent mouth or throat pain
- Unexplained bleeding
- Difficulty chewing
- Difficulty swallowing
- Difficulty moving the tongue or jaw
- Persistent hoarseness
- Unexplained loosening of teeth
- A persistent lump in the neck
Major Risk Factors
Risk can increase with:
- Smoking
- Chewing tobacco
- Gutka and other smokeless tobacco products
- Excessive alcohol consumption
- Certain HPV infections
- Combined tobacco and alcohol exposure
A Simple Rule to Remember
A persistent mouth ulcer or unusual oral patch deserves examination.
IARC specifically highlights oral cancer, along with breast and cervical cancers, as important cancers in India for which early detection strategies can have a meaningful role.
3. Lung Cancer
Lung cancer is the third most common cancer in India overall according to the latest GLOBOCAN estimates. In 2024, approximately 112,659 new lung cancer cases were estimated. Among Indian men, lung cancer was the second most common cancer by number of new cases.
Warning Signs of Lung Cancer
Possible symptoms include:
- A persistent or worsening cough
- Coughing up blood
- Shortness of breath
- Persistent chest discomfort or pain
- Repeated respiratory infections
- Persistent hoarseness
- Unexplained weight loss
- Loss of appetite
- Unusual or persistent fatigue
These symptoms can also occur with conditions such as respiratory infections, asthma or chronic lung disease. The important point is to seek medical evaluation when symptoms are persistent or unexplained.
Major Lung Cancer Risk Factors
Important risk factors include:
- Cigarette smoking
- Other forms of tobacco exposure
- Second-hand smoke
- Certain occupational exposures
- Air pollution
- Radon and other environmental exposures
If you smoke, quitting tobacco is one of the most important steps you can take to reduce your cancer risk.
4. Colorectal Cancer
Colorectal cancer affects the colon or rectum and is becoming increasingly important in India’s cancer burden.
GLOBOCAN 2024 estimated approximately 83,577 new colorectal cancer cases in India, placing it fourth among cancers in both sexes combined. It was also the third most common cancer among Indian men in the latest estimates.
Warning Signs of Colorectal Cancer
Look out for:
- Blood in the stool
- Persistent changes in bowel habits
- New constipation or diarrhoea that does not settle
- A feeling that the bowel has not completely emptied
- Persistent abdominal discomfort or cramps
- Unexplained weight loss
- Persistent weakness or fatigue
- Iron-deficiency anaemia without an obvious explanation
Why Should You Not Ignore Blood in Stool?
Blood in stool can occur for many reasons, including haemorrhoids and other non-cancerous conditions.
However, repeated or unexplained rectal bleeding should not automatically be attributed to piles. A doctor can determine whether further evaluation is necessary.
What Happens During Evaluation?
Depending on symptoms, age and risk factors, your doctor may recommend:
- Medical history and physical examination
- Blood tests
- Stool-based testing where appropriate
- Imaging or colonoscopy when indicated
- Biopsy if a suspicious lesion is identified
5. Cervical Cancer
Cervical cancer develops in the cervix, the lower part of the uterus. It is an important cancer affecting women in India and was the fifth most common cancer overall in the latest GLOBOCAN 2024 estimates.
Approximately 79,360 new cervical cancer cases were estimated in India in 2024. It was the second most common cancer among Indian women after breast cancer.
Warning Signs of Cervical Cancer
Possible symptoms include:
- Abnormal vaginal bleeding
- Bleeding between menstrual periods
- Bleeding after sexual intercourse
- Bleeding after menopause
- Unusual or persistent vaginal discharge
- Pelvic pain
- Pain during sexual intercourse
- Persistent lower abdominal or back pain
Early cervical cancer may cause no noticeable symptoms, which is why appropriate screening is important.
Can Cervical Cancer Be Detected Early?
Yes. Cervical cancer screening can identify cervical abnormalities before they progress to invasive cancer.
Depending on age, health history and applicable guidelines, screening may involve HPV testing, Pap testing or other recommended screening approaches.
IARC identifies cervical cancer as one of the common cancers in India for which screening and early detection can play an important role.
Common Cancer Warning Signs You Should Never Ignore
Although every cancer is different, several symptoms deserve medical attention when they persist or cannot be explained.
Keep this checklist handy:
- An unexplained lump or swelling
- Unexplained weight loss
- Persistent fatigue
- Unusual bleeding
- A sore or ulcer that does not heal
- Persistent cough or hoarseness
- Difficulty swallowing
- Persistent changes in bowel or bladder habits
- Persistent or unexplained pain
- New or changing skin lesions
Remember
A warning sign is not a diagnosis.
The purpose of recognising these symptoms is not to create fear. It is to encourage timely medical evaluation.
Cancer Symptoms in Men vs Women: What Should You Watch For?
Cancer patterns are different in men and women.
Common cancers among Indian men
The latest GLOBOCAN 2024 estimates identify the leading cancers among men as:
- Lip and oral cavity
- Lung
- Colorectum
- Stomach
- Prostate
Common cancers among Indian women
The leading cancers among women are:
- Breast
- Cervix uteri
- Lip and oral cavity

What to Do If You Notice a Possible Cancer Warning Sign
Step 1: Notice the change
Pay attention to symptoms that are new, persistent or worsening.
Step 2: Don’t self-diagnose
A symptom on its own cannot confirm cancer. Avoid relying solely on internet searches or home remedies.

- Biopsy
Step 5: If cancer is confirmed, determine the stage
Treatment decisions depend on factors such as:
- Cancer type
- Stage
- Location
- Tumour characteristics
- Molecular or genetic findings when relevant
- Overall health
- Previous treatments
Step 6: Discuss treatment options with an oncology team
Depending on the diagnosis, cancer treatment may involve:
- Surgery
- Chemotherapy
- Radiation therapy
- Immunotherapy
- Targeted therapy
- Hormonal therapy
- Bone marrow o r stem-cell transplantation for selected conditions
- A combination of treatments
