A new study has highlighted an urgent challenge in India's fight against breast cancer: nearly 13% of women are diagnosed only after the disease has already spread to other parts of the body, a stage known as metastatic breast cancer. The findings, based on data from more than 76,000 women across India's National Cancer Registry Programme, underscore the importance of earlier detection and greater awareness.
What is metastatic breast cancer?
Metastasis occurs when cancer cells spread beyond the breast to distant organs such as the bones, lungs, liver, or brain. At this stage, treatment focuses on controlling the disease and improving quality of life rather than curing it, making early diagnosis critical.
The numbers that matter
The study found that:
- Nearly 13% of women with breast cancer in India had metastatic disease at the time of diagnosis.
- This figure is roughly double that seen in many high-income countries, where around 6% of patients are diagnosed after the cancer has spread.
- Researchers analysed data from over 76,000 breast cancer patients, making it one of the largest studies of its kind in India.
What increases the risk?
Interestingly, the study found that age alone was not a major predictor of metastatic disease. Instead, the strongest risk factors were linked to the tumour itself, including:
- Larger tumour size
- Higher tumour grade
- Cancer spreading into blood or lymph vessels
- Involvement of nearby lymph nodes
These findings reinforce that detecting breast cancer before it grows or spreads can significantly improve outcomes.
Why are diagnoses happening so late?
Experts believe several factors contribute to delayed diagnosis in India:
- Low awareness of early warning signs
- Fear and stigma around breast health
- Delaying medical consultation because a lump is painless
- Limited access to routine screening in many regions
Many women seek treatment only after symptoms become severe, reducing the chances of curative treatment.
Early detection can save lives
Doctors recommend that women become familiar with the normal look and feel of their breasts and seek medical advice if they notice:
- A new breast lump
- Changes in breast shape or size
- Skin dimpling or puckering
- Nipple discharge, especially if bloody
- Persistent pain or swelling
Regular clinical breast examinations and mammograms, when recommended by a healthcare provider, remain among the most effective ways to detect breast cancer early.
