  • Ejaculation and prostate cancer. A study on about 32000 men concluded that men who ejaculate at least 22 times per week are 1/3 less likely to develop prostate cancer.
  • Lack of sex and breast cancer. A case-control study concluded that women that have rare sexual intercourse (less than once a month) are more prone to breast cancer.
  • Pollution and lung cancer. Air pollution has been linked to higher risk of lung cancer and heart failure.
  • Flavonoids against pancreatic cancer. Flavonoids (apigenin, luteolin) from vegetables such as celery and artichoke have been observed to be effective in treating pancreatic cancer.
  • Tanning and skin cancer. Sun tanning or indoor tanning using UV radiation is linked to higher risk of melanoma and other skin cancers.
  • Dental X-Rays and brain tumors. A case-control study discovered a connection between regular dental X-rays and meningioma, a type of brain tumor.

  2. They studied the effect of UV on unprotected skin. They recommend use of sunscreen or clothing for protection.

  3. As I thought, in the case control study authors did not control for sunscreen use. Very difficult to do and a huge confounder.

  4. It's not a case control study, it is a review article of many other articles. They also discuss the mechanism of skin cancer pathogenesis and how different skin types have different sensitivity to UV radiation.
