What causes painless bumps on the skin?

For lumps of unknown cause, you must consider the possibility of cancer. The lump itself can be said to be one of the precursors of cancer, which means that lumps and nodules appear anywhere in the body and should be taken seriously or not taken lightly. Of course, we can also make a preliminary judgment on the induration of these lumps and nodules, and we may wish to make a preliminary judgment from the following aspects.

First of all, on the **surface, the lump can be palpated, and if it is particularly difficult, difficult to push in and touches the edges and corners, you should be vigilant. However, the size of the lump is not a very important criterion, and some large lumps are also very good. If it's soft to the touch and easy to push and rotate, don't worry too much.

Small bumps on the head are mainly benign and include lipomas, epidermal cysts, fibromas, hemangiomas, schwannomas, etc. The softness, mobility, color, pain, and texture of the lump can be used as a basis for judgment, and a small lump in the head is usually first examined by ultrasound and is primarily based on observation or surgical removal, and usually does not require follow-up**.

Mouth ulcer lumps are the most common, but if they do not heal or improve after more than 10 days, a high index of suspicion for malignant ulcers should be taken and careful observation of the center and surroundings. If there is a white spot in the center that cannot be removed by any method, it may be a precancerous lesion of oral cancer. It is necessary to seek medical attention in time to find out the nature of leukoplakia of the oral mucosa.

If necessary, a pathological biopsy may be used to aid in the diagnosis.

The lump usually appears on the neck, but don't worry too much. It is mainly caused by sebaceous cysts and does not cause cancer. However, the aura of leukemia or Hodgkin lymphoma is also located in the neck mass, usually on one side of the neck, which is more rigid.

If the lump near Adam's apple persistently elevated for more than 3-4 weeks, the thyroid gland should be diagnosed in time. Limb lumps and wrists are mostly benign ganglion cysts, but beware of soft tissue tumors.

Soft tissue tumors are a large group of heterogeneous tumors. Depending on the likelihood of metastasis, they are usually divided into benign, marginal and malignant, with less after benign resection, malignant tumors or sarcomas grow invasively and destroy the surrounding normal tissue, local excision is usually rare and can metastasize. ** excision is often required, and regular follow-up is required.

And the cause of itching is the flesh pimple, which also includes filamentous warts. The onset of filamentous warts causes some wart-like growths on the patient's lesions, which are brownish-gray or normal** in color. Although filiform warts usually resolve on their own after a year or two, the disease can be spread through direct or indirect contact.

To sum up, as soon as you feel a lump in your body, you should seek medical attention immediately so that you can ** in time to avoid delaying the condition.

It may be caused by allergies, depending on the shape and specific location of the lump, if it is a protruding lumpy wheal, red rash, etc., it may be urticaria caused by allergies.

It may be mosquito bites, inflammation of hair follicles, superficial lymphatic swelling, pay attention to observation, if it is enlarged and the pressure is obviously painful, can not be pushed, the boundary is not clear, go to the hospital for examination as soon as possible.

**Hard bumps are not painful or itchy, and this condition may be localized common warts. It is also possible to have flat warts, which are large and can also form the symptoms of pimples. It may also be that fibroids are benign.

1. Lipoma, lipoma is mainly due to the proliferation of mature adipose tissue to form tumors, which can appear all over the body, shoulders, abdomen and other locations are relatively common, which is a benign tumor, and generally does not deteriorate, and has no great impact on physical health. Most patients are older and have bad habits such as a greasy diet. 2. Lymphadenopathy is swollen, lymphatic tissues are distributed all over the human body, and common lymph node lumps due to colds, bacterial infections, inflammation and other reasons are benign lymph nodes.

3. Thyroid mass, if a lump is found on the neck, it may be a thyroid mass, which is generally mostly benign, but it should still go to the hospital for diagnosis and treatment to avoid deterioration.
