Before cancer came, this part of my body would itch unbearably

Everyone has experienced "itching". Sometimes it makes people laugh, and sometimes it makes people cry. More than 100 years ago, American psychologists Stanley Hall and Arthur Allyn first defined "itch". Itch can be divided into two types: one is "happy itch", which is caused by stimulation of sensitive parts such as the soles of the feet and armpits, accompanied by unstoppable laughter. Parents and babies first establish an intimate relationship through this kind of itch; the other is "annoying itch", which feels like something small is crawling on the skin, and people can't help but scratch to relieve the itch. Insect bites, dry skin, fungal infections, cardiovascular and cerebrovascular diseases, etc. can all cause this kind of itch.

Studies have shown that itching is a more unbearable feeling than pain. Sometimes the itching can last for several hours, making people feel uncomfortable all over and even unable to sleep. When the "annoying itch" visits frequently, it is a wake-up call for your health.

Ding Yong (pseudonym), 37 years old, started to feel his nose itchy frequently a few months ago. Sometimes the itchiness would wake him up in the middle of the night. Ding Yong thought this phenomenon was very strange, but he did not go to the hospital for such a "minor ailment". However, last week Ding Yong suddenly fainted in his office. When he was sent to the hospital for examination, it was discovered that he had a tumor in his brain. When the doctor learned that Ding Yong had an itchy nose for several months without seeking medical treatment, he told him with great regret that an itchy nose is actually a unique symptom of a brain tumor. If more attention is paid to it, it is possible to detect the presence of brain tumors earlier.

It is reported that many malignant tumors are accompanied by skin lesions during their occurrence and development. Some abnormal skin phenomena, such as itching, erythema, darkening, thickening, etc., may even be early signs of cancer. Cancer treatment specialists point out that skin symptoms are sometimes a sign of visceral malignant tumors, and finding out the cause can help diagnose the tumor early. For this reason, the general public should not be careless about unexplained skin lesions, but should go to the hospital for treatment as soon as possible.

Unbearable itching may be a sign of cancer

In fact, itching can be said to be a very common skin phenomenon, but if there is widespread and long-term itching without any cause, it may indicate a tumor in the adjacent part. For example, if the nostrils are extremely itchy, this is often a unique manifestation of a brain tumor; if the anus is extremely itchy, it may be a manifestation of rectal or sigmoid colon cancer. A survey found that extreme itching of the skin is closely related to malignant tumors of the internal organs. It may be a symptom caused by tumor cells producing biologically active substances such as histamine and proteolytic enzymes that stimulate the sensory nerve endings of the skin, and is a precursor to cancer.

A survey by former Soviet scholar Shaboyev found that 50% of patients with rectal tumors may suffer from skin itching due to the tumor; 25% of patients with genital tumors may suffer from severe itching of the skin near the genitals due to the tumor; among 15 tumor patients, 3 people had itching a few months before the onset of the tumor, and 1 person had skin itching 4 years before the discovery of the tumor. According to statistics, various leukemias, lung cancer, esophageal cancer, etc. all have widespread or severe skin itching. Unbearable itching of the skin all over the body is often a common symptom of Hodgkin's disease, leukemia, myeloma and many cancers.

Blisters are a common clinical manifestation of dermatological diseases, but they may also be a sign of certain malignancies. Studies have shown that about 12% of cancer patients develop herpes zoster-like skin lesions. The older the patient, the higher the incidence rate, and malignant tumors of the lymphatic system are the most common. Esophageal cancer, gastric cancer, intestinal cancer, lung cancer, prostate cancer, etc. may also be accompanied by herpes zoster lesions. If you have symptoms such as erythema, papules, small blisters or clustered wheals and severe painful dermatitis herpetiformis on the posterior armpits, sacrum, buttocks and outer side of the forearms, you should be careful of a "sudden attack" of a malignant tumor.
