I honestly feel very sorry for you and your mother. I'm sure she was a good person. Cancer is a very common problem these days. It can be caused by a variety of reasons, such as: Smoking, obesity, and so on. My dad also had rad four and a half years ago, but luckily we cured the problem by finding information on fenbenlab. At first we thought we would need chemotherapy, but since the stage of the cancer wasn't that big, my dad didn't need chemo. Everything was cured through various medications and other treatments and now he is completely healthy.
