I think so, too. I don't mean to treat cancer entirely by fitness, but to support fitness while receiving medication and fight cancer by strengthening the body's resistance. After all, the ability of cancer cells to spread is very strong, and the time for fitness to take effect is also very slow. For some serious cancers, it can't be said that fitness can definitely drive out cancer cells, or it is necessary to reduce the survival of cancer cells in the body through drug treatment, and then restore their original health level through fitness.

Fitness can bring many benefits, the most common is to improve the body's resistance and immunity and reduce the possibility of getting sick. For diseases like cancer, most people will choose the combination of drug therapy and chemotherapy. Although it can kill cancer cells, chemotherapy is a very harmful treatment. When your cells stay with cancer cells, they will all be destroyed during chemotherapy, which can be said to be "clear between the enemy and me", but fitness can repair the side effects brought by chemotherapy.

It is very important to have a good body to fight cancer cells, and fitness is to exercise our body and keep our body function in the best state to fight cancer cells. Fitness will enhance the function of our body and make our cells more energetic, so that they are not easy to be killed by cancer cells when fighting cancer cells. Fitness can also enhance our immune ability, and prevent bacteria from invading our bodies and aggravating our illness during the weak period after chemotherapy.

Most importantly, fitness can keep us in a good mood, which is the most needed factor to treat diseases. When we are sick, the doctor will tell us to keep a good attitude, which is conducive to our physical recovery. Mental state is very important to our health. If we can't keep a good attitude, we will sigh and worry about something every day. Over time, even healthy people will eventually get sick.
