No, cancer is actually many diseases. They hold some commonalities, but it’s not one thing. That’s why chemotherapy can straight cure some cancers and do nothing for others. That’s also why we have hundreds of chemotherapy drugs. Also, not even all cancers have tumors. You have solid tumor oncologists and then oncologists who specialize in blood and lymphatic cancers, “liquid cancers”. In addition, cancer does not arise from one mutation. It’s a set of mutations that allow cancer to occur. You need mutations for growth, mutations for preventing cellular death, mutations for stealing energy, mutations for hiding from the immune system. Your body, right now, has probably millions of cells that could be candidates for cancer. They either kill themselves or your immune system nukes them. You really need the stars to align on this stuff to get actual cancer. And then, it’s not like the cancer stops mutating. Cancer becomes resistant to chemotherapy through mutations. Cancer is “smart”, it will even temporary slow its own growth (metabolism) to intake less chemotherapy through treatment.
