18. Changes in Bladder Control
You find that your bathroom habits are changing and you need to urinate more frequently. This could be a sign for several types of cancer. If you suffer from an over active bladder, problems urinating, or not being able to completely empty your bladder, then this is a sign of a problem with your urinary tract and possibly a sign of cancer.
This could be a cancer sign of the bladder or the prostate if you’re a man. And if you’re a woman, it could mean ovarian or cervical cancer.
