According to the data released by the International Agency shows that 1 in 5 people worldwide will be diagnosed with cancer in their lifetime, and 1 in 8 men and 11 women will die of cancer.

However, 50.6 million people are still alive within 5 years after being diagnosed with cancer.

Every year the physical examination is normal, why do I still get cancer?

Because cancer is menacing, most cancers have no obvious early symptoms, so many people are afraid of cancer. And many people will choose regular physical examinations to understand their physical condition.

Even so, some patients are still diagnosed with cancer.

It is inevitable that some people will think, why does cancer still come to the door after obviously having a physical examination?

For cancer screening, these 2 misunderstandings must be corrected

Cancer screenings, which can detect early-stage cancers early, are attracting increasing attention, and many are even being tested at an expensive cost.

In fact, understanding the myths of early cancer screening will help to understand cancer more fully and control its development.

1. General physical examination is equivalent to cancer screening

In recent years, physical examination has become a recruitment benefit for many units, and employees are usually organized to have a physical health examination every one to two years.

Typically, everyone has a physical exam from time to time, and many people also see physical exams as cancer screenings. But the truth is that general health checkups do not include tumor screening, nor do they include cancer screening.

The purpose of tumor screening is to detect some tumors in the body as early as possible, and to analyze some risk factors that may cause tumors. It may play an intervening role in the unhealthy lifestyle of some screeners.

2. Only need to check once

Some people go through cancer screening and no problems are found. You will think that there will be no problems in recent years or even in the future, so you will not be screened for cancer in the future.

But the fact is that abnormal genetic mutations can cause cancer , which also makes cancer unpredictable, so we can't just rely on cancer screening to detect cancer.

And, even with regular annual screenings, it is possible to find cancer cells between screenings. Therefore, normal screening results do not guarantee a worry-free period of several years.

At the same time, for high-risk groups of cancer, the frequency of screening should be appropriately increased.

3. Too much trust in PET-CT examination

PET-CT is widely used in the field of cancer diagnosis. Not only is it expensive, but it can detect tumors as small as one centimeter, leading many to blindly believe it, thinking that PET-CT's full-body scans can detect cancer.

However, the existence of "false positive" and "false negative " results does not guarantee its accuracy. Cancer screening requires a comprehensive diagnosis and a multipronged approach to ensure accurate cancer screening.
In addition, the radiation dose of PET-CT whole-body scanning is very large, so the risk of harm to the body needs to be considered. It is not usually recommended as a cancer screening method for people without symptoms of cancer.

In addition to examination, cancer patients should be careful not to fall into these dietary misunderstandings;

1. The more expensive the fungus, the better the anti-cancer effect

The lentinan contained in some mushroom foods has anti-cancer effects, so cancer patients should eat fungi such as Flammulina velutipes, shiitake mushrooms or Hericium erinaceus, but the more expensive, the better the anti-cancer effect.

Some people choose some imported fungi in order to pursue the effect, thus wasting a lot of financial resources, which is not worth advocating.

2. Cancer should reduce diet and starve cancer cells to death

Cancer patients must have adequate nutritional support before undergoing chemotherapy, radiotherapy and drug treatment to enhance their ability to resist tumors.

Cancer patients must ensure adequate nutritional intake and supplement protein, such as fish, eggs, milk and soybean products.

According to a study by the American Cancer Society, cancer patients should consume at least 20% more calories than usual to maintain the normal functioning of the body.

Although cancer is scary, people don't have to worry too much. If you unfortunately suffer from this disease, you must face it bravely, maintain an optimistic mood, and supplement nutrition in time, so that you can better fight the disease.

You must know that there are many cases of cancer being cured. As long as you pay attention to a balanced diet, pay attention to rest, maintain a good attitude, have regular checkups, and actively cooperate with doctors for relevant treatments, there is still hope for recovery.
