Dear one,
If homosexuality is a mental illness, then it cannot possibly be a sin, can it. After all, to sin you must make an act of your will to do so, right?
Your assertion that homosexual men are 4000 times more likely to get anal cancer than heterosexual men is a gross inaccuracy. To quote Wikipedia:

Risk factors
Human papillomavirus examination of squamous cell carcinoma tumor tissues from patients in Denmark and Sweden showed a high proportion of anal cancers to be positive for the types of HPV that are also associated with high risk of cervical cancer (90% of the tumors from women, 100% of the tumors from homosexual men, and 58% of tumors from heterosexual men). In another study done, high-risk types of HPV, notably HPV-16, were detected in 84 percent of anal cancer specimens examined.
Sexual activity: Having multiple sex partners or having anal sex, due to the increased risk of exposure to the HPV virus.** Homosexual and bisexual men are 17 times more likely to develop anal cancer than heterosexual men.**
Smoking: Current smokers are several times more likely to develop anal cancer compared with nonsmokers.
Immunosuppression, which is often associated with HIV infection.
Benign anal lesions (inflammatory bowel disease (IBD), hemorrhoids, fistulae or cicatrices). Inflammation resulting from benign anal lesions, such as hemorrhoids and anal fistulas, has been considered to cause a predisposition to anal cancer.
