Melanoma: 8 Things You Need To Know

Written by : LifeStyle Team

In a recent study, researchers have outlined five important points about malignant skin cancer called melanoma.

  1. The study published in CMAJ (Canadian Medical Association Journal) highlighted the following five points about melanoma.

  2. Sun exposure is an important factor in the development of melanoma, so it often appears on the face, neck, arms and torso, where sun exposure is common.

  3. Melanoma can also occur on areas with minimal sun exposure, such as palms and soles of the feet.

  4. A specific mitogen-activated pathway is linked to mutations causing melanoma and genomic sequencing helps in identifying markers for diagnosis and treatment.

  5. About 10 per cent of melanomas are challenging to diagnose as they may be pink, red, clear or normal skin-coloured.

  6. Patients with any suspicious skin lesions should be referred to dermatology. Coloured lesions with any of the ABCDE criteria -- Asymmetric shape, irregular Border, Colour variation, Diameter greater than 6 mm (about the size of a pencil eraser) and Evolution (change) -- should be considered suspicious.

  7. According to the study conducted by the University of Leeds, funded by Cancer Research UK and published in Cancer Research, smoking may limit body's ability to fight dangerous form of skin cancer like melanoma. In detail, melanoma patients with a history of smoking cigarettes are 40 per cent less likely to survive their skin cancer than people who have never smoked.

  8. While for most cancers, risk increases dramatically with age, but a recent study has found that the height of a person could also make them more prone to cancer. The University of California study, published in the journal Proceedings of the Royal Society B, says tall people are at greater risk of cancer.
