According to a BBC report, a study of 122,345 people in California suggests that the gay men are twice as likely to have had cancer. It is not clear from this study why this might be.
The survey was based on interviews of "survivors" so is not a true representation of the number of cancer cases. It was not possible to conclude that the gay men have a higher risk of cancer. Further research would be needed to determine if homosexual men were actually getting more cancer or had greater survival rates than heterosexuals.
There was no such link in women. However, lesbians and bisexual women were reported to have poorer health after cancer than heterosexuals.
