Welcome to the forums chenyu

I really like your post, and I agree with you. Unfortunately, chemotherapy, radiation, and cuting the body parts are the only way for treatment. Radiation, and chemotherapy kills all cells in the body, including the good cells, that is why a patient lose hair after going through chemotherapy. These methods can also cause further mutations. We know that they are not the most favourable treatments, but they do work. A friend's mother had cancer, and she had to undergo chemotherapy, but luckily, she was cured. So these treatments do work, and it is easier to deal with them when they are still benign, so only the affected area needs treatment. Hopefully, in the future, we might be able to help cancer patient using stem cells. So we could remove the affected organ, and replace with it.
I also hear a lot about Chinese medicine, such as using some kinds of mushrooms, anyone know more about that?
