The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).What are the signs that chemo is working?
Complete response - all of the cancer or tumor disappears; there is no evidence of disease. A tumor marker (if applicable) may fall within the normal range. Partial response - the cancer has shrunk by a percentage but disease remains. A tumor marker (if applicable) may have fallen but evidence of disease remains.What are the signs that chemo is not working?
Signs that a person's cancer is not responding to chemotherapy include: a tumor growing or not shrinking. cancer spreading to other areas of the body, a process called metastasis. cancer symptoms returning.What happens if chemo doesn't shrink tumors?

Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.Do tumors shrink after first chemo?
Chemotherapy is a powerful cancer treatment that uses drugs to destroy cancer cells. It can shrink a primary tumor, kill cancer cells that may have broken off the primary tumor, and stop cancer from spreading. But it doesn't work for everyone.Can tumor markers go up during chemo?
Chemotherapy treatment can cause a temporary increase in tumour marker levels. This happens because chemotherapy causes cancer cells to die quickly and release large amounts of the tumour marker.Can blood tests tell if chemo is working?
