Please choose the correct ending to complete the given sentence: Health: [header] How to know if you're at high risk for prostate cancer [title] Consider your age. [step] There is a very strong correlation between your age and your risk of developing prostate cancer. You are unlikely to develop prostate cancer before the age of 40, and about six in ten cases of prostate cancer are in men over the age of 65.

Ending1: [substeps] People over 45 may have high risk for having prostate cancer. Seniors and people over 65 can have some risk. Ending2: [substeps] Even if you are diagnosed with prostate cancer later in life, it is key to understand that many men outlive their prostate cancer. What this means is that, even if you are diagnosed with prostate cancer, many forms are very slow-growing and do not need treatment. Ending3: You may be at risk for not developing a prostate cancer, or you may be at higher risk of developing a cancer later. [substeps] While menopausal women can develop prostate cancer, there are currently no studies suggesting that women younger than 40 should not develop prostate cancer. Ending4: If you are not a man in your 40's, you are at a higher risk. Women in the late 30's, for example, are at a higher risk of developing cancer.
