After cancer cells appear, it does not necessarily mean they will develop into cancer.
That's because our body has a variety of protective mechanisms, among which the most important is tumor suppressor genes.
Only when tumor suppressor genes are lost or become dysfunctional can cancer cells settle down within the human body and eventually turn into tumors.
Why are young people less prone to cancer, while the risk increases for the elderly?
Mainly because the immune system of the elderly becomes weaker.
In addition, the more frequently cells renew themselves, the higher the probability of errors.
No one knows precisely when this patient's splenic tumor appeared. Some cancer cells can lurk stealthily and develop insidiously, like Sima Yi from the Three Kingdoms, patiently waiting. Only when a defensive weakness appears in the patient's body do they seize the opportunity, rapidly growing into a malignant tumor.
