One of the most famous examples is Song Mei-ling, who got breast cancer at the age of 65-67 and lived until she was 105 years old after two surgeries. The earlier the stage, the earlier the treatment, the greater the chance of non-recurrence. It is also related to whether the patient can get good rehabilitation, recuperation, correcting bad habits, adjusting emotions and diet. For example, estrogen-progestin receptor positive breast cancer with very low proliferation index rarely recurs, but triple negative breast cancer or epidermal growth factor receptor strong positive breast cancer is more likely to recur, depending on the individual.
