Types of melanoma

This information is on melanoma. There are other types of skin cancer known as non-melanoma skin cancers. These include basal cell carcinoma (rodent ulcer) and squamous cell carcinoma.

There are four main types of skin melanoma:

  • Superficial spreading melanoma is the most common type. In women, the most common place for it to start is on the legs. In men it’s on the chest and the back. The melanoma cells usually grow slowly at first and spread out across the surface of the skin.
  • Nodular melanoma is the second most common type. It can grow more quickly than other melanomas and is usually found on the chest, back, head or neck.
  • Lentigo maligna melanoma is usually found in older people in areas of skin that have had a lot of sun exposure over many years. It’s often found on the face and neck. It develops from a slow-growing precancerous condition called a lentigo maligna or Hutchison’s freckle, which looks like a stain on the skin.
  • Acral melanoma is the rarest type and is usually found on the palms of the hands, soles of the feet, or under fingernails or toenails. It’s more common in people with black or brown skin and isn’t thought to be related to sun exposure.

Rarely, melanoma can start in parts of the body other than the skin. It can start in the eye (ocular melanoma). Or it can start in the tissues that line areas inside the body, such as the anus or rectum (anorectal melanoma), nose, mouth, lungs and other areas.

The skin

The skin is divided into two main layers: the outer layer known as the epidermis and a layer underneath called the dermis.

What is melanoma?

Melanoma is a type of skin cancer. It develops from cells in the skin called melanocytes.

Cancer and cell types

Cancers are grouped into types. Types of cancer often behave and respond to treatments in different ways.

How is it treated?

There are five main types of cancer treatment. You may receive one, or a combination of treatments, depending on your cancer type.

Why do cancers come back?

Sometimes, tiny cancer cells are left behind after cancer treatment. These can divide to form a new tumour.
