Patient Information Leaflets (PILs)

These Patient Information Leaflets (PILs) are specially written by the British Association of Dermatologists (BAD). A small selection is available in booklet format and can be ordered by filling in an order form.

The BAD has been awarded The Information Standard certification for the process it employs to develop information products aimed at the general public, which include PILs, Sun Awareness Campaign materials, and other information products.

The BAD shall hold responsibility for the accuracy of the information published, and neither the scheme operator nor the scheme owner shall have any responsibility for costs, losses, or direct or indirect damages or costs arising from inaccuracy of information or omissions in information published on the website on behalf of the BAD.

Please note:

  1. There are thousands of different skin complaints, therefore, the focus of the British Association of Dermatologists' PILs production is on the most common, rarest or debilitating skin conditions.
  2. The offer to provide details of source materials used to inform British Association of Dermatologists' PILs is for instances where the advice provided perhaps does not reflect local practice, and not an offer to conduct literature searches or supply bibilographic materials for your own research.

Melanoma - Stage 3

Melanoma is a type of skin cancer, which arises from the pigment cells (melanocytes) in the skin. In a melanoma skin cancer the melanocytes become malignant and multiply excessively. One of the most important causes of melanoma is exposure to too much ultraviolet light in sunlight. The use of artificial sources of ultraviolet light, such as sunbeds, also increases the risk of getting a melanoma.

Melanocytes make a brown/black pigment (known as melanin), and often the first sign of a melanoma developing is a previous mole changing in colour or a new brown/black lesion developing. Most frequently there is darkening in colour but occasionally there is loss of pigmentation with pale areas or red areas developing. This melanoma on the skin is known as the primary melanoma.

In around 20% of patients diagnosed with melanoma, the melanoma spreads to the lymph nodes. This is classed as stage 3 melanoma.

Lymph nodes, or lymph glands, are found in our lymphatic system which is part of the body’s immune system. The (skin) lymphatics are tiny channels in the skin, which move lymph fluid around the body to the lymph nodes in the groin, under the arms (arm pits) and in the neck. As part of the immune system, the lymph fluid can carry bacteria and even cancer cells with it. Once contained within the lymph nodes, the immune system attempts to destroy them. If the immune system fails to destroy such cancer cells they can grow within the lymph nodes creating a lump. However, the lymph nodes can also swell for other reasons such as infection (e.g. when we have a sore throat there may be swollen glands in the neck).
