The cancers that most often affect men are prostate, colon, lung and skin cancers. Doing what you can to prevent them — or find them early when they are easier to treat — can help you lead a longer, healthier life.

Prostate Cancer

What is it: Prostate cancer is the second most common cancer in American men. The risk grows with age. Having close family members with it raises your risk. The good news: It’s highly curable.

What you can do: Talk about your risk factors at your next checkup. In general, screening should start in your 40s or 50s. Changes in urination, painful ejaculation or pain in the back, hip or pelvis areas are reasons to call your doctor sooner.

Colon Cancer

What is it: Cancers of the colon and rectum are called colorectal cancer. They have many common features. Most start as a growth, or polyp, on the inner lining of the colon or rectum. Some change into cancer over time, but not all polyps become cancer.

What you can do: Talk to your doctor about what screening tests you need. Regular screening can often find problems early, when a problem is small and hasn’t spread. That makes it simpler to treat. For colorectal cancer, screening may even prevent cancer because a polyp can take 10 to 15 years to grow into cancer. A doctor can remove it during a screening test like a colonoscopy.

Lung Cancer

What is it: Lung cancer is a leading cause of cancer death in men. Smoking causes most lung cancers, but nonsmokers can also develop it.

What you can do: Don’t smoke or use tobacco. Avoid second-hand smoke. Limit your exposure to radiation.

Skin Cancer

What is it: Skin cancer is the most common kind of cancer. There are several types. The severity and treatment options vary by type. Basal and squamous cell skin cancers are often found in areas exposed to the sun. That includes the arms, neck and head, but they can happen in other areas. They are very common but are often easily treatable. Melanoma is a more dangerous type of skin cancer that is likely to grow and spread.

What you can do: Keep an eye on your skin. If you see any new spots or changes in moles that concern you, have a doctor take a look. Avoid sunburn and tanning in the sun or tanning beds. Use sunscreen with a SPF of 15 or higher. Try to stay in the shade when you’re out during the day, especially between 10 a.m. and 4 p.m. Cover up with clothing, a hat and UV-blocking sunglasses. The Skin Cancer Foundation recommends regular visits to a dermatologist for a skin exam.

Lower Your Risk for Cancer

When it comes to lowering cancer risk, the American Cancer Society says men should:

  • Avoid all forms of tobacco.
  • Keep a healthy weight.
  • Eat healthy foods, such as fruits and vegetables.
  • Keep moving with regular exercise.
  • Limit how much alcohol you drink.
  • Take steps to protect your skin.
  • Know your family health history.
  • Get regular checkups.
