If chemo is supposed to kill all cancer cells then why have to go through radiation
Both post bilateral mastectomy.
I asked the exact same question - apparently the chemo goes through the blood and takes care of any possible cancer that may have gotten into our system. That's the big picture. The radiation takes care of any possible stray cells that may have flaked off and are in our breast tissue which deals with it possibly still coming back in our breast tissue. If there's no lymph node involvement than we don't need the chemo, just radiation because there's very little risk of the cancer having spread into the blood and to other organs. I hope that helps.
I did not have any lymph nodes involved but had chemo. The reason why is it lessens the chance of recurrence and will kill any stray cells that might not have been removed during surgery
It's complicated because I did chemo first to shrink the tumor; then a lumpectomy to remove what was left. I too thought doing radiation was not needed after all that but once it was explained to me the benefit to me outweighed the risks. Also I know a young lady who did not elect the radiation and cancer showed up in her other breast and traveled to her brain and this was only months after she had chemo and mastectomy.She passed months later. Im not trying to frighten u but I think u should do ur own research. make ur decision on what u can live with and feel comfortable with. God bless.
I think it depends on the stage of cancer. Initially I was Stage I later Stage IIa. I had the Oncotype DX Assay test and my result was 13 which meant chemotherapy would be little benefit. I didn't need radiation because there was no sign of cancer in my chest muscle.
I had no lymph nodes positive and was told before surgery I would not need radiation but because I'm Grade 3 I needed chemo. Then surgeon was not able to get clear margins because tumor was too close to skin.....now I'm being told I have to go through both.....but of chemo is supposed to kill all cancer cells then what is the need to go through both? I know I need to ask oncologist but don't see him for another 3 weeks while my scars heal more.
