What are the signs of melanoma

Doctor's Answers 2

Melanoma is a serious type of skin cancer that if left untreated, can potentially spread to other organs in the body and cause serious complications. The common signs to look out for would be a changing pigmented lesion or mole. These can be easily remembered as the ABCDE of a changing mole:

A: Asymmetrical shape or pigment pattern

B: Border that is irregular

C: Colour changes within the mole or a mole with different colours

D: Diameter of over 6mm but some early melanomas may be smaller

E: Evolving mole with change in size, shape or colour, or Elevation of mole, although early melanomas may be flat

Other not to be missed signs would be a non-healing wound or sore.

It is also important to assess your risk factors for developing a melanoma or other skin cancers. Risk factors that would put you at higher risk would include:

  • Being older >60 years

  • Lots of previous sun exposure and a history of sunburns

  • Previous history of skin cancer including melanoma

  • Previous history of pre-cancers such as dysplastic naevi or actinic keratoses

  • Family history of skin cancer including melanoma

  • You are taking medicines that suppresses your immune system

  • You have multiple >100 moles on your body

In summary, if you are considered high risk and have a changing mole or skin lesion, please see your Dermatologist early to have it assessed in detail. A regular skin screen every 12 months is recommended to ensure all your moles are fine. Skin cancers are very treatable if caught early.

What are other symptoms of melanoma besides irregular moles?

A melanoma may develop from a normal mole which then changes over time. A melanoma normally changes in shape, size and colour, sometimes slowly or sometimes very quickly. If a mole becomes very black, bleeds or have irregular borders and different colours within, do speed-dial your dermatologist office for an appointment.

What are the different types of skin cancer?

Yes apart from the most dangerous melanoma, there are 2 other types of skin cancer. Skin cancer can be broadly divided into non-melanoma skin cancer or the more dangerous melanoma. Non-melanoma skin cancer includes basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). BCCs account for vast majority of skin cancers and are most often found on sun exposed areas of people who spend a lot of time outdoors. BCCs are generally not life threatening as they rarely spread to the rest of the body. However, if left untreated, they continue to grow and can destroy surrounding tissues.
