Urology 16 years experience
In other ways.: The development of bladder cancer has little to do with the frequency of urination. It has everything to do with changes to the lining of the bladder, mostly due to exposure to toxins in the urine, such as from cigarette smoke & industrial chemicals. Inherited genetic factors play a role as well. For those that have developed bladder cancer, one of the symptoms can be frequent urination.

No: If you donated blood a month ago, you should not be having pain. This would most likely be from phlebitis or irritation to the vein. I would have someone take a look at this or call the facility that drew the blood.

Very Variable: If you quit smoking, your tissues can quickly recover from the damage especially if you have been eating foods with lots of antioxidants like red, orange, yellow fruits and same color plus green leafy vegetables...So the cancer cells may not develop at all unless you have a strong family history of cancer and your immunity has been severely compromised.
