Diagram of a prostate tumor pressing on the urethra
Prostate cancer is the uncontrolled growth of cells in the prostate. It is often detected through blood tests for prostate-specific antigen, followed by a biopsy. Most prostate tumors (diagram pictured) cause no health problems, and are managed with surveillance. Dangerous tumors can be surgically removed or destroyed with radiation therapy. Those whose cancer spreads receive hormone therapy, targeted therapy, and eventually chemotherapy. Most tumors are confined to the prostate, and 99% of men survive ten years post-diagnosis. Those whose tumors have metastasized to distant body sites have a poorer prognosis; 30% to 40% are still alive five years after diagnosis. Each year 1.2 million men are diagnosed with prostate cancer and 350,000 die of the disease, making it the second-leading cause of cancer in men. Prostate tumors were first described in the mid-19th century. Hormone therapies were developed in the mid–20th century, resulting in Nobel Prizes for their developers Charles Huggins and Andrzej Schally. (Full article...)
Many people know that if someone reverts an article more than three times in 24 hours (3RR), they may be blocked to prevent edit warring. But did you know that:
Although reverts on different articles do not count towards the limit, different reverts on the same article do count. So if you revert Paragraph A twice and Paragraph B twice in 24 hours, you have made four reverts and may be blocked.
If you revert three times, wait for 24 hours and start reverting again, you may be blocked for 'gaming' the rule. The three-revert rule is an electric fence, not an entitlement.
Although you cannot be blocked for repeatedly reverting vandalism, many Wikipedians mistake edits for vandalism when they are not. For example, edits that do not respect the neutral point of view policy are not vandalism.
The easiest way to avoid being blocked for reverting is to revert as little as possible and discuss with your fellow editors instead. Some editors limit themselves to one or no reverts a day. Select categories on Wikipedia are limited to 1RR (one revert rule). Those articles will have an edit notice to apprise you of their special status. For 1RR you may only revert one edit in the entire category per 24-hours.
