Brief Introduction to Body Surface Tumors Body surface tumors are tumors that grow on the surface of the human body. Body surface tumors can also be divided into benign and malignant. However, most surface tumors are benign tumors and have basically no impact on human health. Some do not require treatment at all, while others only require a minor operation, which is neither painful nor any sequelae.

Common body surface tumors 1. Skin hemangiomas are recommended for medical treatment. Please check this page. This disease is extremely common and appears as a semi-spherical ball the size of a pinhead and the size of a soybean, with a soft texture. Hemangiomas are higher than the skin and are cherry red in color. They can occur anywhere on the skin, but are most common on the trunk. It usually appears in adulthood, increases with age, is persistent, and generally has no subjective symptoms. This is a localized increase and dilation of capillaries in the skin. Although the number is large, it has no impact on human health and does not require treatment. If some of them grow too large and cause inconvenience to work and life, electrocautery or cryotherapy can be performed. Hemangioma in other parts of the body (click to view medical guide),

2. Lipoma This is a common benign tumor of subcutaneous adipose tissue that is cyst-like, round, and enveloped. It can occur anywhere in the body and can be classified into congenital, simple and multiple lipomas. The cause of the disease is still unclear. Multiple lipomas are soft but have no tenderness or other symptoms and generally do not require treatment.

3. Subcutaneous cysts

They are also benign tumors. They usually appear on the head, neck and around the eyes, nose and mouth, and also often appear on the front and back midlines of the body. Subcutaneous cysts vary in size, and the contents of the cysts are fat-like material. It needs to be surgically removed, and the effect is good.

4. Sebaceous cyst

Also known as sebaceous cyst, it is a pseudotumor caused by obstruction of sebaceous gland secretion. It can occur in any part of the human body, but it is more common in the head, Around the ears, top of neck, shoulders, back, etc. The size of the penis varies, generally within two centimeters, round, localized, and mostly adhered to the epidermis. Ulceration, bleeding and infection are common, and in a few cases, malignant transformation is possible. Therefore, once this tumor is discovered, it should be surgically removed as soon as possible.

5. Ganglion cyst Strictly speaking, this cyst is an undesirable tumor, which is formed after the degeneration of the connective tissue in the tendon sheath. It mostly occurs in middle-aged and elderly people, and is more common on the back of the wrist, the instep of the foot, etc. The capsule is filled with gel-like material, the surface is smooth when touched, and feels mobile, cystic and elastic. There is generally no tenderness and it will harden when the contents are full. Small cysts do not require treatment and sometimes disappear on their own. Slightly larger cysts can be absorbed and disappeared if they are compressed. For patients with large cysts and obvious symptoms, surgical removal can be performed.

6. Fibroids are benign tumors that occur in subcutaneous fibrous connective tissue or muscle fiber tissue. They are mostly round or oval, hard, mobile, slow growing, and painless. Fibroids have the possibility of malignant transformation, and once discovered, they should be surgically removed as soon as possible.

7. Malignant melanoma

This tumor commonly occurs in the skin, eyes and other parts of the body. Most of them are transformed from moles, freckle-like nevus and normal skin due to chemical stimulation. Black moles are benign and do not require treatment. However, if it is often scratched, rubbed, picky, and corroded, it can cause malignant changes. The rapid growth of moles, deepening of blackness, surface ulceration, serous fluid exudation, bleeding, infection, worsening of pain, and sometimes radial expansion of pigment are all manifestations of transformation into malignant melanoma, and the cancerous part should be surgically removed in time.

8. Skin cancer is a malignant tumor originating from epithelial cells. Skin cancer mostly occurs in the head, face, hands and other parts of the elderly that are exposed to the sun for a long time. It is closely related to burns and long-term chronic physical and chemical stimulation. In addition, lupus erythematosus, keratinoma, chronic sinus tracts and fistulas, epidermoid cysts, foreign body granulomas, chronic skin ulcers, etc. all have the possibility of cancer. Skin cancer has a low degree of malignancy and is not easy to metastasize. If detected early and treated promptly, it can be cured.
