What are the signs before cancer occurs? Huaxi doctors remind you to detect these 8 changes in your body as early as possible

We often find that many cancer patients are not aware of or do not pay attention to the signals sent by the body in the early stages. By the time they realize something is wrong, the best time for treatment has been missed.

In order to avoid regrets, today we invited Dr. Guo Wenhao from the Cancer Center of West China Hospital of Sichuan University to talk to you:

" Why are there no symptoms in the early stages of cancer? What changes in the body may be a sign of cancer? How to screen for common tumor diseases? " Once something goes wrong, it's too late

Why are there no symptoms in the early stages of cancer?

Many people have heard this saying: No matter how normal a condition is, once you go to the hospital, you probably have cancer. This means that cancer is too difficult to detect in the early stages!

Many cancer diseases are discovered early due to regular physical examinations, while many cancer diseases are discovered late because people usually go to the hospital only when they feel something is wrong with their body.

Why there are no symptoms in the early stages of cancer? It all starts with the body's immunity:

After experiencing the new coronavirus, everyone understands that the immune system is an important basis for maintaining life. Without the immune system, any unknown virus can knock down a person.

Simply put, our body is likened to a palace, and the immune system is the imperial guards. Their common functions are to identify and kill .

We are usually not aware of its existence, but when they find something "abnormal" in the human body, such as the arrival of "destructive elements" such as the cold virus and the new coronavirus, it will enter combat mode, and the human body will then show obvious discomfort symptoms such as fever, pain, redness, swelling, suppuration, cough, asthma, vomiting and diarrhea.

The difference of cancer cells is that they are not foreign. Most of them are mutated from normal cells in our body. Some of these mutated "destructive molecules" will be recognized and eliminated by the immune system, while others may learn to "disguise themselves as normal cells" and escape.

In other words, the reason why there are no obvious symptoms in the early stages of cancer is because the immune system mistakenly believes that cancer cells are "internal friends" and there is no risk of being killed, so no discomfort symptoms are caused.

Then, when the cancer cells have "lurked" in place, they will begin to spread and metastasize wildly one day. The human body will then feel uncomfortable, but it will be too late.

The reason why 80% of malignant tumors in my country are already in the advanced stage when discovered is because of this reason!

The magic of life is

It will send a signal to remind you!

I believe that everyone who has lived for many years has some experience in the magic of life. Thinking, logic, emotions, self-healing ability, etc., remind us all the time that it is great to be alive and there are so many experiences!

But cancer doesn’t want you to be well. As a carrier of life, your body certainly doesn’t want that! So it will always try to send you signals to remind you to pay attention to these “destroyers”!

For most people, common signs (symptoms) include:

① Unexplained weight loss and fatigue

If the weight loss is more than 5% within six months to a year, and there are symptoms such as anorexia, fatigue, and easy fatigue, it is recommended to find out the cause as soon as possible, unless it is due to weight loss or deliberate dieting, or benign diseases such as abnormal blood sugar, abnormal thyroid function, chronic diarrhea, etc.

② Unexplained lumps and nodules

When unexplained lumps or nodules appear in the body, such as breast or testicular lumps, subcutaneous nodules, or enlarged superficial lymph nodes in the neck, armpits, and groin, you should pay attention to it.

Especially if it is accompanied by redness, swelling, pain, abnormal blood vessels, abnormal color changes, rapid enlargement in a short period of time, etc., you must see a doctor immediately!

③ Unexplained persistent pain

Pain may be caused by chronic diseases, bone lesions, etc., but if it is severe pain, you must find the cause of the pain and guard against the occurrence of tumors.

④ Long-lasting cough

Half of lung cancer patients have chronic cough when diagnosed, and breast cancer, colon cancer, kidney cancer, prostate cancer, etc. that spread to the lungs can also cause persistent cough. It is recommended to get checked early.

⑤ Shortness of breath

Shortness of breath is also one of the early symptoms of lung cancer. Long-term shortness of breath can easily lead to respiratory failure. It is necessary to find out the cause as early as possible and receive targeted treatment as soon as possible.

⑥ Unexplained bleeding

Very typical tumor symptoms, covering almost most tumor diseases, specific reference is as follows:

▲ If you have blood in your stool or vomit blood, you should rule out the possibility of colon cancer or stomach cancer;

▲ Coughing up blood or blood in sputum should alert you to lung cancer;

▲ Irregular vaginal bleeding, non-menstrual bleeding, and postmenopausal bleeding may be related to gynecological tumors such as endometrial cancer and ovarian cancer;

▲ Painless hematuria or dysuria, beware of urinary system tumors;

▲ If nose bleeding is not caused by trauma, be careful to rule out the possibility of nasopharyngeal cancer.

⑦ Changes in stool

Long-term constipation, diarrhea, or alternation of the two should alert you to the occurrence of gastrointestinal tumors.

Malignant tumors of the pancreas or liver may also affect the absorption of nutrients by the digestive tract, resulting in varying degrees of diarrhea and steatorrhea. If these symptoms persist for a long time , get checked out as soon as possible.

⑧ Persistent digestive abnormalities

If you have long-term indigestion, loss of appetite, acid reflux, heartburn, and upper abdominal pain, don’t just ignore it as “stomach problems”. Be careful, it may be stomach cancer or esophageal cancer.

Cancer is a very complex disease and it is not caused overnight;

It is because of the accumulation of time, procrastination and lack of attention that we miss the best period for treatment, so I emphasize again that regular check-ups are important!!!
