Because cancer is a disease, if it is found early, the cancerous place will be removed before it spreads, and as long as it does not spread later, it will basically be the same as normal people.

Moreover, Song Meiling has enough funds to support her to find the top medical team at that time, tailor a detailed treatment plan for herself, remove her cancerous place in time, take good care of her later, and have regular physical examinations to ensure that cancer can be found in time and any minor problems can be removed in time.

Therefore, Song Meiling can live longer than the average person. Non-malignant tumor+timely operation+long-term physical examination is the secret of Song Meiling's longevity.
