The claim that running cures breast cancer is unscientific. Running can, to a certain extent, play a role in preventing breast cancer and assisting breast cancer recovery, but there is no curative effect. A lot of data show that bad dietary habits, lack of exercise, obesity and so on will increase the incidence of breast cancer. Therefore, running improves the immunity of the body, which can reduce the incidence of breast cancer to a certain extent, but does not have a curative effect. When treating breast cancer, doctors will use medication or surgery according to the grade of the disease and the patient’s own condition; the principle of local treatment plus systemic treatment will also be adopted in the treatment in order to improve the curative effect. If you have breast cancer, it is recommended that you go to a regular hospital in time and make professional treatment plan according to the doctor’s advice, so as to avoid delaying your condition. Patients should maintain a good mindset and moderate physical exercise, which is conducive to the recovery of the disease.
