Introduction:
Skin cancers are divided into three main types of Basal cell carcinoma, Squamous cell carcinoma and Melanoma, based on the abnormal cell development and proliferation of the type of skin cells. While Basal-cell carcinoma grows slowly and is more localized to the skin tissue, Squamous-cell carcinoma is more aggressive and malignant and can lead to metastatic far distance spread to other body tissues and could be fatal. Melanomas that arise from the melanocytes or skin pigment cells, are the most aggressive, malignant and metastatic, that killed Bob Marley.
While the sun is the source of life on earth and our own life in different aspects depend on its shinning, such as regulation of our circadian rhythm, sleep-wake cycle, and the color of our skin, its excess could contribute to more than 90% of skin cancers cases. The risk nowadays are higher due to a thinner ozone layer, and also the increase fad of artificial tannings as another common source of ultraviolet radiation. The longer and more intense exposures, such as from childhood and the sensitivity of the skin’s subject, for example the white skins, the living zones, such as regions with intense sunshine like Australia and New Zealand, and also the less defensive immune system, the more risk of cancer.

Despite all these, and the skin cancer being the most common of all cancers world wide, the early intervention of the skin cancers, even melanoma through removal of the locus of the cancer such as the mole, radiotherapy and medications, have increased the survival rate of all the skin cancers higher than other cancers, close to 90% recovery rate. That takes us to the sad story of Bob Marley, who due to his religious beliefs, refused the full treatment of his melanoma on his toe from 1977, so the cancer spread to his brain and killed him mercilessly on 11 May 1981, at age only 36 and deprived the whole art of music and his global friends form a longer legendary career.

Bob Marley, a musical icon, the father of reggae and an international messenger of love and peace, who started with band “The Wailers” , and a national symbol for Jamaica, with all his spirituality, yet could not survive from a small mole on her toe that finally spread to his brain and killed him. His songs such as “One love”, “Is this Love”, “Redemption Song”, “Waiting in Vain”, “Satisfy my Soul”, “O’Woman don’t cry”, “Buffalo Soldier”, “I shot the Sherriff”, “Jamming” and more has no need for an introduction as he is know and loved still to this day by billions. He could easily be the only human’s messenger and representation in popular music and culture. Unfortunately his religious commitment to Rastafari, not to allow the amputation of his cancerous toe so to prevent the spread of the melanoma, deprived him of such a great life and his fans to enjoy his music years longer.
