Acidic body is more prone to cancer?
The so-called 'acidic' or 'alkaline' tests are mainly based on the pH of our blood. It actually has a standard range, and this range is very narrow, which means that our body's pH must be within this range. It's normal to be within. It's not good to be over-acid or over-alkaline. It will lead to disease and affect our health.
The tumor is a genetic disease. Our cell's genes have changed, causing cell growth to lose control and become a tumor. The growth of one of our cells has lost control and turned it into a tumor.
We do not have direct scientific evidence to show that acidic physique can increase the incidence of cancer.
The more expensive the anti-cancer screening is, the better? No need!
Director of Cancer Prevention Department, Fudan University Cancer Hospital, Professor Zheng Ying
Cancer screening is basically a three-fold examination: imaging, two-celled, and there is an examination of related cancer markers.
But it is very important that these inspections are all done. The choice of which tests to use is based on a careful assessment of cancer risks and then on which tests need to be performed. In general, the costs of inspections are also not It will be expensive.
Second, there are some expensive inspection methods, such as genetic testing, which have not been validated by large-scale populations and are therefore not suitable for cancer screening.
Therefore, cancer screening is not judged on the basis of price, but the more suitable it is, the better.
Aspirin prevents gastrointestinal cancer? Inaccurate!
Deputy Director of Colon Surgery, Fudan University Affiliated Tumor Hospital Professor Xu Wei
This sentence is actually half true. Aspirin can indeed prevent the occurrence of various digestive system tumors including gastric cancer, colon cancer, pancreatic cancer, and the cardiovascular system, which can prevent the occurrence of thrombosis.
However, it also has many side effects: long-term use of aspirin will cause bleeding; second, aspirin has toxic side effects on the digestive system, so some people use aspirin will produce nausea, abdominal pain, it is also a certain poison for the liver and kidneys side effect.
So, at present, not all people are suitable for using aspirin. What kind of person is suitable for use, what kind of dose must be confirmed by more studies.
Does MRI have less radiation?
Professor Peng Weijun, Director of Department of Radiology, Fudan University Cancer Hospital
Now many people are skeptical about magnetic resonance imaging. In fact, magnetic resonance is absolutely radiationless.
CT is imaged by X-rays, so it has some radiation. Frequent CT examination is not recommended. However, MR uses the hydrogen protons in the body to obtain information in the body through resonance. Therefore, it is No radiation. It is one of the safest inspection techniques in imaging today.
Moreover, MRI has very high resolution of soft tissues and is very suitable for neurological, bone, joint and abdominal examinations. Therefore, patients and family members can rest assured. Nowadays, low-dose spiral CT is recommended for lung cancer patients, which is equivalent to one year in nature. The amount of radiation can be checked under the guidance of a doctor.
