Types of skin cancer

The skin is made up of a number of different cells, many of which are constantly moving. As round basal cells under the surface ascend to replace dead, peeling squamous cells on the surface, they flatten out. Merkel cells provide skin the capacity to perceive touch, whereas Melanocytes tan the skin in the sun. These cells may grow into skin cancer if they become injured.

Skin malignancies are all dangerous and should be treated as soon as possible. However, depending on the types of cells involved, skin cancer forms, treatment choices, and prognoses vary greatly. Healthowealth has gathered the types of skin cancer in this post.

Basal cell

According to the American Cancer Society, basal cell carcinoma accounts for more than 80% of the more than 3 million instances of skin cancer identified each year. These malignancies start in the skin’s basal cell layer, which is the epidermis’s lowest layer.

This kind of skin cancer is most common in parts of the skin that are exposed to the sun the most, such as the head and neck. Basal cell tumors develop slowly and seldom spread to surrounding lymph nodes or even to distant areas of the body, which is known as metastasis. However, if left untreated, this can happen, thus early discovery and treatment are critical.

Basal cell tumors can sometimes reoccur in the same spot where they first started. Patients who have previously experienced basal cell carcinoma are more likely to acquire a new basal cell carcinoma elsewhere. Within five years of their initial diagnosis, up to 50% of these individuals may develop a second basal cell carcinoma.

Basal cell carcinoma recurrence

According to the American Cancer Society, basal cell carcinomas are the most frequent kind of skin cancer. These malignancies start in the basal cell layer of the epidermis, which is the lowest layer of the skin.

Patients who have had basal cell carcinoma before are more likely to have recurrent basal cell carcinoma. Basal cell tumors can reoccur in the same spot where they first appeared or elsewhere in the body. Basal cell carcinoma recurrence is anticipated to occur in up to 50% of cancer patients within five years of the first diagnosis.

Basal cell carcinomas are slow-growing tumors that rarely metastasize or spread to adjacent lymph nodes or other regions of the body. However, early identification and treatment are critical.

After basal cell carcinoma therapy, it’s critical to do regular skin self-examinations to check for new symptoms, such as atypical growths or changes in the size, shape, or color of an existing lesion. Skin cancers are more common in sections of the body that are exposed to the sun, but they can also occur in locations that are not exposed to the sun. Any new symptoms or unusual changes should be reported to your oncologist or dermatologist.

Patients with basal cell carcinoma should be on the lookout for symptoms of recurrence since they are at a higher risk of getting other skin malignancies. It’s difficult to predict a patient’s risk of recurrence of basal cell carcinoma, however, recurrence is more likely in those who:

  • Have you ever had eczema or dry skin?
  • Have you been exposed to a lot of UV light? (such as in tanning beds)
  • Original carcinomas were discovered many layers down in the skin.
  • Original carcinomas that were more than 2 cm in diameter

After basal cell carcinoma therapy continued follow-up care is required for several years. Follow-up checkups and self-examinations are strongly suggested after your initial cancer treatment to assist discover and diagnose skin anomalies.

Squamous cell carcinoma

These malignancies are the second most frequent kind of non-melanoma skin cancer, accounting for around 20% of all non-melanoma skin cancers. They arise from the flat squamous cells that make up the epidermis, the skin’s outermost layer.

This form of skin cancer develops in parts of the skin that have been exposed to the sun, such as the neck, ears, face, or back of the hand, but it can also occur in scars, skin ulcers, or the genital region. Squamous cell carcinomas are slow-growing tumors that seldom spread (metastasize). They are, however, more prone than basal cell carcinomas to penetrate fatty tissue beneath the skin or spread to other parts of the body.


Types of skin cancer: Melanoma
Types of skin cancer: Melanoma

Melanoma is cancer that develops in the skin cells known as melanocytes, which generate the dark pigment melanin. When exposed to the sun, these cells darken as a defensive reaction to protect the deeper layers of the skin from the detrimental effects of UV radiation.

Merkel cell carcinoma

Merkel cells, along with nerve endings, provide the skin with its sense of touch, and this rare but deadly form of skin cancer starts in them. Merkel cell carcinomas are more frequent in sun-exposed parts of the skin, such as the face and scalp. This kind of skin cancer is more common in those over 50 who have a weakened immune system. Merkel cell carcinomas can spread from the brain to the bones, liver, and lungs.

Skin tumors that are uncommon

Other types of skin cancer are extremely uncommon, such as:

  • Human herpesvirus 8, commonly known as Kaposi sarcoma-related herpes virus, causes Kaposi sarcoma (KS). On the skin, this cancer generally shows as lesions or tumors. Tumors can develop in the mouth, lungs, or gastrointestinal system. Patients infected with HIV, the virus that causes AIDS, account for the majority of KS cases in the United States. KS, on the other hand, can strike people with a severely weakened immune system.
  • Actinic keratosis is a precancerous development that, if left untreated, can progress to squamous cell carcinomas. These growths can be discovered in clusters on skin that have been affected by UV radiation.
  • Skin lymphoma, often known as cutaneous lymphoma, is non-Hodgkin lymphoma. The lymph nodes, which are tiny glands dispersed throughout the body that generate disease-fighting T-cells and B-cells, generally known as lymphocytes, are where most instances of lymphoma develop. Other lymphoid tissue, such as the spleen, bone marrow, and skin, can also develop lymphomas. This uncommon malignancy can cause a rash or lumps on the skin.
  • Keratoacanthomas are benign (non-cancerous) tumors that develop slowly and eventually disappear. Keratoacanthoma tumors that do not stop growing are frequently treated as squamous cell carcinoma.
