Gay and bisexual men are more likely to smoke than heterosexual men. Smoking raises their risk for lung cancer. And for each person who dies from smoking, 30 other people are living with a serious health problem linked to the habit. Some of these problems are stroke, lung disease, and heart disease.

If you have HIV, smoking can reduce your life expectancy a lot. That's even if you have the HIV under control.

Anal cancer is fairly rare among heterosexual males. It's much more likely to occur in gay and bisexual men. The main risk factor for it is having anal sex with men. The risk of getting anal cancer is even greater if you've been exposed to HPV (the human papillomavirus). The risk is also higher if you:

• Have had many sex partners or unprotected sex
• Smoke
• Have a weakened immune system as a result of HIV

Anyone can get skin cancer. You are at a higher risk, though, if you have:

• Fair skin
• A history of bad sunburns at a young age
• Frequent and prolonged sun exposure
• A weakened immune system
• Close family members with skin cancer

All men are at risk for prostate cancer. In fact, there are more new cases of prostate cancer found each year in men than any other cancer. But it's more likely to occur in:

• African-American men
• Those with a family history of prostate cancer
• Men older than age 50

Some studies have found that men may be at a higher risk for this type of cancer if they have HIV or AIDS. Testicular cancer tends to happen in younger men between ages 20 and 34. Men also have a higher risk for it if they:

• Are white
• Have undescended testicles
• Have a family history of testicular cancer

This cancer happens most often in men who are age 50 and older. It's also more likely in men with:

• Inflammatory bowel disease
• Colon or rectal polyps
• Personal or family history of colon cancer

These lifestyle factors also play a role in the risk for colon cancer:

• Smoking
• Being overweight
• Not being active
• Eating a diet with a lot of red and processed meat

If you have risk factors for any of these cancers, you can help lower your risk by:

• Eating a healthy diet
• Exercising and being active
• Limiting your alcohol intake
• Not smoking

It's also important to get regular checkups and cancer screenings. Talk with a healthcare provider about the schedule that's best for you. These visits play a role in your overall health. They also help find cell changes (precancers) early before they become cancer. Finding cancer when it's small and hasn't spread often makes it easier to treat.
