I don't want to scare anyone, but don't wait if at all possible. While some tumors grow slowly, some grow excedingly quickly. I am now in my second cancer recovery and had I waited either time, the results would have been far worse. My breast cancer was the size of a BB and everyone I counseled said "wait." Luckily, I didn't. The cancer had already spread to two lymph nodes and was the most aggressive type there is. I would have been dead within a year had I waited, and that was 18 years ago.
This time, I noticed blood in my urine the first of February, 2018. Tested, CT scanned and 3 cm tumor found. Surgery March 1 and the tumor was 9cm long and had invaded the muscle wall for a High Grade, T2 staging. My daily radiation and once weekly chemo starts Monday and, after 33 rounds of radiation, the "real" chemo to attack the cells in my blood starts. I do not yet know the timing for that treatment.
