Do fingers know if there is cancer in the body? Reminder: If there are 3 abnormalities in the hands or if a tumor has invaded

Mr. Li, who is 55 years old and usually in good health, accidentally discovered six months ago that his skin began to have obvious pigmentation. Although the symptoms were quite significant, they were not painful or itchy, so he didn't pay much attention to them.

One month ago, Mr. Li noticed that his fingers were starting to swell and unable to bend or extend. He was very anxious now and took it seriously. He quickly went to the hospital for treatment. After a series of examinations, it was found that there was a tumor of about 4 centimeters in the lungs, and he was finally diagnosed with pulmonary phosphorus cancer.

This result surprised Mr. Li and his family. He usually has no lung symptoms, neither chest tightness nor coughing or phlegm. How could he possibly have lung cancer?

Doctors remind that the enlargement and thickening of the tip of the finger, resembling a club, is called clubbing finger, also known as mallet finger or drumstick finger, mainly indicating compensatory hyperplasia of the finger after hypoxia. The clubbed finger itself is not uncomfortable, so it is easy to be ignored, but it is a signal of many diseases. In clinical practice, many lung disease patients will have clubbed fingers. If you suddenly find that your fingers have become thicker or larger, you must be alert and go to the hospital for examination as soon as possible.

The hand is a holographic reflection area of the human body, like the second face of the human body, not only carrying out various functions of daily life, but also hiding the health code of the body. When these abnormalities occur, it may indicate that your physical health has sounded an "alarm".

1. Clubby Finger

Clubby fingers are characterized by the proliferation and thickening of the end of the finger, appearing as a club like swelling. Its features include a significant widening and thickening of the end phalanx, an arched protrusion of the nail from the root to the end, and a basal angle of at least 180 degrees between the skin on the back of the index finger and the nail. Normally, it is an obtuse angle of 160 degrees, with the thumb being the most prominent. After the appearance of clubbed fingers, the obtuse angle is no longer visible, sometimes even at the opposite angle, and the volume of the distal finger bone increases. The main reason for the appearance of clubbed fingers is mostly due to the patient's lack of oxygen. When there is insufficient oxygen in the body, insufficient oxygen supply through blood vessels to the end of the body, that is, the fingers or toes, will lead to the proliferation of blood vessels at the end, resulting in clubbed fingers.

Club shaped finger can be seen in various diseases, mainly related to the presence of heart disease, lung disease, and digestive system disease. For example, in congenital heart disease, many patients may experience the fusion of arterial and venous blood, which means that the patient's venous blood may enter the arteries, leading to a decrease in arterial blood oxygen saturation and resulting in illness.

In addition, clubbing is also a typical manifestation of poor lung function, commonly seen in chronic lung abscess, bronchiectasis, chronic obstructive pulmonary disease, lung cancer and other diseases. According to statistics, the incidence of clubbing in lung cancer patients is 1.6% to 9.4%, because patients inhale insufficient oxygen through the lungs, resulting in clubbing. Digestive system diseases, including Crohn's disease, intestinal amoebiasis, chronic ulcerative colitis, multiple colon polyps, etc., may also cause clubbing.

2. Finger mole mutation

If abnormal changes such as enlargement, bleeding, ulceration, itching, color changes, rough edges, etc. are found on the black mole on the finger or toe, it is necessary to be vigilant and may be malignant melanoma. It is necessary to go to the hospital for examination in a timely manner. Melanoma, also known as malignant melanoma, is a type of malignant tumor originating from melanocytes. It is commonly found in the skin and can also appear in mucous membranes, choroids, and other areas.

It is a highly malignant type of skin tumor that is prone to distant metastasis, so early diagnosis and treatment are particularly important. If black vertical lines appear on the nails, common causes include pigmentation caused by nail trauma, nail nevi, and nail melanoma.

Among them, onychomycosis is a relatively common benign tumor in clinical practice, referring to the border nevi in the methyl matrix, which can occur at any age. If it persists after appearance, a small number may become malignant melanoma, and the probability of cancer transformation is generally 1% to 2%.

3. Finger swelling and pain

Finger swelling may be the manifestation of lymphedema, which may be related to breast cancer. When the local lymph nodes in the armpit of the patient metastasize, resulting in limited lymph flow in the upper limb, swelling of the upper limb, including the hand, will occur.

In addition, after lymph node resection, breast cancer patients may have lymphedema, leading to finger swelling. Patients with rheumatoid arthritis of the fingers may experience swelling of the finger joints, typically with uniform swelling around the joints, such as spindle shaped swelling in the proximal interphalangeal joint. The more severe the joint swelling, the more severe the pain and tenderness, and even severe pain. It may also be accompanied by morning stiffness, joint friction sounds, limited joint movement, or deformities. If a patient experiences persistent finger pain, especially at night or in the morning, it may be a sign of cancer. For example, bone cancer may cause bone pain, while synovial sarcoma may cause finger joint pain. In addition, if bronchogenic carcinoma grows at the apex of the lung, as the tumor grows, it may compress the brachial plexus nerve, causing swelling of the brachial plexus nerve and resulting in symptoms of hand pain in its controlled area, which may be accompanied by local numbness.

Compression of the sensory center by intracranial tumors can cause hand pain symptoms, and hand movements are generally not significantly affected at this time; The enlargement of upper limb osteosarcoma can compress the ulnar nerve and cause symptoms of hand pain.

Pay attention to these 5 changes in your nails!

1. Yellowing and thickening of nails

If nails turn yellow, the most common cause is onychomycosis. It is recommended that patients go to a regular hospital's dermatology department for examination and a clear diagnosis. If nails grow slowly, lack luster, and turn yellow and thick, it often indicates a problem with the lymphatic system, such as yellow nail syndrome.

In addition, patients who smoke for a long time can also cause their nails to turn yellow due to smoking. As age increases, elderly patients may also experience dull nails and yellowish nails due to nail hypertrophy.

2. Small indentations on nails

Normal individuals may occasionally have needle like indentations on the surface of the nail, but obvious indentations are more common in psoriasis, alopecia areata, and eczema with proximal nail matrix damage. Deep needle like indentations are common in psoriasis, while small, shallow, geometrically distributed indentations are common in alopecia areata.

3. Blue or purple nails

Blue nails generally indicate severe hypoxia in heart disease patients, that is, low blood oxygen levels in the blood, insufficient oxygen supply to the body, suffocation or circulatory failure, leading to congestion in the body. If a patient has congenital heart disease, insufficient blood supply to the heart during the onset of the disease can lead to ischemia and purple discoloration of the fingernails, accompanied by symptoms such as arrhythmia, fatigue, and pale complexion. If the color of the nails is dark and dark purple, and it cannot be relieved, it indicates poor blood circulation at the end of the fingers. Be alert to the occurrence of pulmonary heart disease and coronary heart disease, and it is recommended to seek medical attention in a timely manner.

4. Bosch line

Bosch line is the appearance of multiple horizontal stripes on the nail, often indicating malnutrition or suffering from a serious disease that will temporarily affect the growth of the nail, such as coronary atherosclerotic heart disease, leading to coronary artery thrombosis, slow blood flow, and affecting the growth of the nail, which will lead to the appearance of Bosch line.

5. Brittle nail

Brittle nail is a condition where the nails become brittle and prone to cracking. Patients may experience thinning and brittleness of the nail deck, making it easy to crack. The appearance of brittle nails is often related to chronic diseases of the nail matrix, frequent exposure to chemicals, chronic inflammatory or keratinizing skin diseases such as psoriasis, chronic eczema, as well as peripheral circulation disorders, hypochromic anemia, myxoedema, and hypoparathyroidism.
