Which cancers do not affect life expectancy? Mainly early cancer. If it is an early cancer in situ, it will basically not affect the life span. For example, breast cancer in situ, cervical cancer in situ, lung cancer, stomach cancer, and gastric cancer also have cancer in situ, because the gastroscope was discovered at once, and the forceps, that is, the biopsy forceps of the gastroscope, can be removed at once. Some people just need to do endoscopic resection in the early stage, and it will not affect their life span. There are also some cancers, such as thyroid cancer, which are differentiated thyroid cancer, and their life expectancy will not be affected after surgical resection, because thyroid cancer is found relatively early because the ultrasound level is too high. If the technical resolution is too high and the technology is superb, the lesions below 1 cm can be found very early, so thyroid cancer can also be found early. Some prostate cancers are also very early. After being discovered very early, it is also possible that the disease will always accompany you for life. Therefore, early cancer in situ, early cancer or some well-differentiated skin cancer, for example, may not be committed for life after surgical resection. Therefore, it is promising that early cancer will survive for a long time and never commit crimes.
