Early tumor screening is very necessary, the benefits of early detection is less cost, less pain, the most critical, you can get a good survival period, and to ensure the quality of survival. So what are all the ways that cancer can be detected early? First of all, it is also the tumor marker blood test that is usually done in the basic physical examination. Tumor markers that can be detected by drawing blood include: breast cancer, lung cancer, esophageal cancer, stomach cancer, colorectal cancer, pancreatic cancer, liver cancer, prostate cancer and ovarian cancer. However, there are many cases in which cancer is diagnosed but the blood test is normal, so this indicator can only serve as a certain reference. There are many other examination methods depending on the location of the cancer. First of all, for brain tumor, head CT and brain MRI can be done; for nasopharyngeal tumor, nasal endoscopy and head CT can be done; for thyroid tumor, thyroid ultrasound can be done; for breast tumor, breast ultrasound can be done; for breast tumor, breast ultrasound can be done.

Gastroendoscopy can detect tumors of the esophagus, stomach and duodenum. Rectal tumors, liver tumors can be detected by liver ultrasound and abdominal CT. abdominal CT is also used to detect tumors of the gallbladder, pancreas and kidneys. Gynecological ultrasound as well as cervical pictures can be used to check for tumors of the cervix as well as ovaries.
