Cancer, also known as malignant tumorsIt is a disease caused by the abnormal mechanism of controlling cell growth and proliferation, and it is also a disease that makes people smell and discolor, and it has becomeThe number one killer of human life and health
Malignant tumors are called malignant because they differentiate quickly and easily and rapidly throughout the body.
In the past ten years, the incidence and mortality of malignant tumors have continued to rise, threatening people's life safety and quality of life.
In fact, for malignant tumors, the body has a defense mechanism, especially in the early stage of malignant tumorsThe body will release some "distress signals", and every time it is giving patients a chance to prevent cancer, but many people think that those are minor problems and fail to grasp them in time!
Therefore, we must pay attention to the signals sent by the bodyPay attention to observation, catch malignant tumors from these "clues", and early identification can save lives!
Persistent fatigue and malaise
Under normal circumstances, as long as you have a good rest after fatigue, you can quickly adjust, but extreme tiredness and general fatigue should be taken seriously.
BecauseFatigue is one of the most common manifestations of cancer development, such as:Stomach cancer, bowel cancerPeople may feel fatigue early in the course of illness and often do not improve with rest.
Sudden weight loss
If the weight of the unknown cause appears to be decreasing every week,In the exclusion of diabetes, tuberculosis, hyperthyroidism, etc., cancer should be considered first
BecauseCancer can affect a person's digestive function, causing persistent weight loss or weight gain, such as:Esophageal cancer, stomach cancer, lung cancer, pancreatic cancer, liver cancerand many other cancers can cause sudden weight loss.
Therefore, if you have a regular diet, no exercise**, dieting habits and the above diseases, but there is a sudden weight loss or weight loss for no reason, it should be taken seriously.
There is a lump on the body
Sudden appearance of a palpable abnormal lump on the superficial or surface of the body, as in"Hard bumps" that can be felt on the neck, armpits, breasts, or other parts of the body, with a fixed position, a hard texture, unclear edges to the touch, and a lot of movementPoor ......Even if it is not painful or itchy, as long as it does not subside for a period of time, you must seek medical attention in time.
If foundThe lump continues to grow, especially nodules that enlarge rapidlyA general tendency to be malignant may be, and we should attach great importance to it.
Unexplained bleeding
If there is no trauma to the body but bleeding inexplicably, this is a very abnormal phenomenon, especially intestinal bleeding.
Intestinal bleeding includes:Oral cavity, nasal cavity, urethra, **, etc., all parts of the outward opening, as long as there is abnormal bleeding or frequent bleeding, it is likely to be a very important early warning sign of cancer, should be paid attention to, timely medical treatment for relevant examinations.
Such as partialBleeding of unknown origin may occur in women, especially in postmenopausal women, should be vigilant when bleeding occurs againCervical cancer, endometrial cancerand so on** the occurrence of cancer.
Taking cervical cancer as an example, it will form cancerous tissue similar to cauliflower, and patients may involve large blood vessels during examination or sexual life, causing bleeding, such as contact bleeding in women.
In addition,Patients with frequent blood in the stool should be screened for gastrointestinal cancer, while recurrent hemoptysis and blood in sputum should be suspicious of lung cancer.
Persistent anti-** fever
Cancer can cause tissue necrosis, reduce the patient's immunity, and make it easy to develop infection, which will produce endogenous pyrogens that affect the thermoregulatory center, so that patients have frequent colds, fevers and other symptoms.
, such as:Leukemia, lymphomaand other malignant tumors can affect the immune system, and the body may manifest itself as a persistent fever in order to combat this problem.
In addition, there is a group of cancer patients that sometimes appear"Tumor fever"., which is mainly manifested as:Fever in the late afternoon and evening is regular, relieved in the early hours of the next morning, which is to:Lymphoma presents most typically
Therefore, if there is an intermittent, unexplained, and intermittent fever, it must not be treated as a cold, and you must seek medical attention in time.
Persistent pain
The growth and spread of cancer cells will invade tissues and organs, causing them to varying degrees of damage, and at the same time, the cancer will compress the nerves and surrounding tissues, which will also cause patients to experience painful symptoms.
Malignant tumor pain is characterized by persistent pain, which cannot be relieved even after using some basic analgesics, and some patients may have recurrent pain, including vague abdominal pain, epigastric distention, etc, should be vigilantStomach cancer, bowel cancer, esophageal cancerand so on** the occurrence of cancer.
In addition,Brain cancer can present as a long-term headache; Rectal cancer and ovarian cancer may cause lower back pain; Unprovoked stomach pain is not only the stomach, but also other tissues or organs, such as liver cancer
Therefore, when there is pain in the body, even if it is not caused by malignant tumors, it is necessary to pay attention to it, seek medical examination in time, and treat the symptoms.
Stool habitual traits
Some cancers of the gastrointestinal tract cause changes in stool regularity or stool consistencyIf the stool is thin, the stool is pus, the stool is bloody, the stool is mucus, the stool is black, etc., or constipation and diarrhea alternately, it is necessary to be vigilantColorectal cancershould go to the hospital for examination as soon as possible.
Clubbing is present
Clubbing is common in patients with squamous cell carcinoma, adenocarcinoma and small cell lung cancer and is one of the early symptoms of lung cancer.
In the early stage, the tumor of lung cancer patients can secrete hormones such as growth hormone, vasodilators, and long-acting thyroid stimulators, which can lead to clubbingIt usually presents with hyperplasia and hypertrophy of the ends of the fingers or toes.
If the patient's cardiopulmonary function is usually good, but clubbing appears, it is necessary to be alert to the occurrence of cancer.
