Oncologist Prescribes Daily Sunshine to Boost Cancer Prevention

Summary
- Sunlight-derived vitamin D helps fight cancer cells
- Vitamin D supplements less effective than natural sunlight
- Ideal vitamin D levels for cancer prevention are 30-50 ng/ml
On November 15, 2025, Delhi-based oncologist Dr. Sudipto De revealed that getting enough sunlight is crucial for cancer prevention. In an Instagram video, Dr. De explained how vitamin D from sunlight can help fight cancer cells and reduce the risk of death from the disease.
The oncologist noted that while vitamin D supplements may provide some benefits, they are not as effective as the vitamin D obtained naturally from sunlight exposure. According to research, those with the right vitamin D levels, between 30 to 50 nanograms per milliliter, have a lower risk of colorectal, breast, and prostate cancer.
To help meet the recommended vitamin D levels, Dr. De suggests getting at least 15 to 20 minutes of sunlight each day, while also using sunscreen. He added that a balanced diet with foods like fish, eggs, and fortified milk can also contribute to maintaining healthy vitamin D levels. If levels are found to be low, the oncologist recommends discussing supplements with a doctor.
