Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. Wikipedia
My late wife was first diagnosed with thyroid cancer and almost lost her voice. She was operated on and heer voice was very raspy for a while, like Neville Wran, but returned after 3 months. Later it was found in the womb and she had a histerectomy. Then it was diagnosed in her endometrium. She was treated with chemo and radiation including radiation targeted at the source of cancer using a radioactive isotope. She was informed by her oncologist that she was clear, and would no longer need to see her. Within 3 months she was back in hospital where it was detected in her chest. She passed away a couple of weeks later.
With my bladder cancer, once diagnosed, the bladder was removed along with my prostate and pelvic lymph nodes, to prevent it spreading. In recovery, I had nine weeks of chemo. This kills fast growing cells. Fast growing cells include white blood cells, and blood tests before each treatment identified my blood was too weak to proceed, so I required a couple of blood transfusions. However, it did ensure that I have been able to lead a somewhat normal life for almost 11 years.
The side effects? I now pee through an opening in my belly, called a stoma, into a plastic external bladder stuck to my belly with an adhesive barrier. Total permanent erectile dysfunction (nothing works).With lack of use your manhood starts to atrophy after six weeks, so I've read, so you can imagine what happens after 11 years. My manhood is now smaller than an acorn.
