Smatra se da razvoj melanoma započinje nekontroliranim rastom i dijeljenjem genetički transformiranih melanocita . Naime, kada je koža izložena UV zračenju, nastaju mikrooštećenja na staničnoj razini koja potiču melanocite na proizvodnju melanina. Time se koža ”brani” od daljnjeg štetnog utjecaja zračenja, a u obrani organizma sudjeluju i imunosne stanice koje uklanjaju oštećene stanice. Međutim, tijekom vremena se takva oštećenja DNA u stanicama kumuliraju, što posljedično dovodi do nastanka mutacija i nekontroliranog rasta i dijeljenja melanocita. The stage of a cancer is a term used to describe the size and depth of the melanoma, and whether it has spread. Knowing the stage of your cancer helps doctors decide on the best treatment for you. In some cases (3-7%) mutated versions of BRAF and NRAS undergo copy-number amplification. [60] Metastasis [ edit ] Early signs of melanoma are changes to the shape or color of existing moles or, in the case of nodular melanoma, the appearance of a new lump anywhere on the skin. At later stages, the mole may itch, ulcerate, or bleed. Early signs of melanoma are summarized by the mnemonic "ABCDEEFG": [14] [15] For example, a 2016 study on rats found that herbal melanin may be able to prevent the formation of stomach ulcers. This suggests that melanin could play a role in the protection of the gut.

Melanin: Definition, function, benefits, and more

More research needs to be done before scientists can confirm whether melanotan increases your risk of developing skin cancer. Still, this remains one of the biggest concerns around the use of tanning injections.However, many melanomas present as lesions smaller than 6mm in diameter, and all melanomas are malignant when they first appear as a small dot. Physicians typically examine all moles, including those less than 6mm in diameter. Seborrheic keratosis may meet some or all of the ABCD criteria, and can lead to false alarms. Doctors can generally distinguish seborrheic keratosis from melanoma upon examination or with dermatoscopy. [ citation needed]

prisutnost većeg broja madeža na koži. Iako prisutnost velikog broja madeža na koži nužno ne znači da će se razviti melanom, takve su osobe ipak pod povećanim rizikom od njegove pojave. Obično se kao granica uzima broj od sto madeža – one osobe koje imaju više od sto madeža na koži pod povećanim su rizikom, iako neki stručnjaci smatraju da taj broj može biti i manji (50-100). Takve osobe moraju biti osobito oprezne prilikom izlaganja suncu i redovito, barem jednom godišnje raditi pregled čitave kože i svih postojećih madeža. Posebno se trebaju pratiti atipični madeži ili tzv. displastični nevusi koji su obično veći od 6 mm i nepravilnih rubova. For example, daily application of sunscreen with an SPF of 50 or higher can help minimize the effects of UV light on the skin. a b Vos T, Allen C, Arora M, Barber RM, Bhutta ZA, Brown A, etal.

UVB light (wavelengths between 315 and 280nm) from the sun is absorbed by skin cell DNA and results in a type of direct DNA damage called cyclobutane pyrimidine dimers. Thymine, cytosine, or cytosine-thymine dimers are formed by the joining of two adjacent pyrimidine bases within a DNA strand. Somewhat similarly to UVB, UVA light (longer wavelengths between 400 and 315nm) from the sun or from tanning beds can also be directly absorbed by skin DNA (at about 1/100 to 1/1000 of the efficiency of UVB).

ŠTO JE MELANOM I KAKO NASTAJE?UV radiation exposure from tanning beds increases the risk of melanoma. [22] The International Agency for Research on Cancer finds that tanning beds are "carcinogenic to humans" and that people who begin using tanning devices before the age of thirty years are 75% more likely to develop melanoma.

The term malignant melanoma is becoming obsolete because the word 'malignant' is redundant as there are no benign melanomas. Nakon toga slijedi klinički pregled u kojem liječnik detaljno pregledava sumnjivu tvorbu, ali i čitavu kožu te vidljive sluznice pacijenta pod jakim svjetlom. Pigmentne promjene liječnik će promotriti dermatoskopom – ručnim mikroskopom kojim se vizualizira epidermis te dio dermisa, a koji je važan alat u dermatološkoj dijagnostici. U slučaju da je neka od tvorbi sumnjiva, sljedeći dijagnostički korak će biti ekscizijska biopsija , odnosno uklanjanje čitave promjene zajedno s dijelom okolne zdrave kože ako je promjena manja ili rjeđe incizijska biopsija, odnosno uklanjanje dijela promjene ako je ona veća ili na nezgodnom mjestu.

Need to select "melanoma"The first English-language report of melanoma was presented by an English general practitioner from Stourbridge, William Norris in 1820. [161] In his later work in 1857 he remarked that there is a familial predisposition for development of melanoma ( Eight Cases of Melanosis with Pathological and Therapeutical Remarks on That Disease). Norris was also a pioneer in suggesting a link between nevi and melanoma and the possibility of a relationship between melanoma and environmental exposures, by observing that most of his patients had pale complexions. [162] He also described that melanomas could be amelanotic and later showed the metastatic nature of melanoma by observing that they can disseminate to other visceral organs.

Ipilimumab was approved by the FDA in March 2011 to treat patients with late-stage melanoma that has spread or cannot be removed by surgery. [187] [188] [189] Fair- and red-haired people, persons with multiple atypical nevi or dysplastic nevi and persons born with giant congenital melanocytic nevi are at increased risk. [38] A number of treatments improve survival over traditional chemotherapy. [124] Biochemotherapy (chemotherapy with cytokines IL-2 and IFN-α) combined with BRAF inhibitors improved survival for people with BRAF positive melanoma. [124] Biochemotherapy alone did not improve overall survival and had higher toxicity than chemotherapy. [124] Combining multiple chemotherapy agents (polychemotherapy) did not improve survival over monochemotherapy. [124] Targeted therapies result in relatively short progression-free survival (PFS) times. The therapy combination of dabrafenib and trametinib has a 3-year PFS of 23%, and 5-year PFS of 13%.

Važno je naglasiti da se ne uklapaju svi melanomi u sve navedene kriterije , stoga je dobro javiti se liječniku za bilo kakvu novonastalu neobičnu promjenu na koži ili bilo kakvu promjenu već postojećeg madeža. Osobitu pažnju treba obratiti na promjene koje ne cijele, krvare, rastu ili se mijenjaju oblikom i bojom.

Melanotan 1 vs. Melanotan 2

Surgery / excision biopsy to remove the melanoma and a small area of surrounding skin is the main treatment. Melanin is a UV-absorbing agent and is able to protect the skin against the effects of UV light on the skin’s surface. It also offers protection against UVB and blue light. When melanomas have spread to the lymph nodes, one of the most important factors is the number of nodes with malignancy. Extent of malignancy within a node is also important; micrometastases in which malignancy is only microscopic have a more favorable prognosis than macrometastases. In some cases micrometastases may only be detected by special staining, and if malignancy is only detectable by a rarely employed test known as the polymerase chain reaction (PCR), the prognosis is better. Macro-metastases in which malignancy is clinically apparent (in some cases cancer completely replaces a node) have a far worse prognosis, and if nodes are matted or if there is extracapsular extension, the prognosis is worse still. In addition to these variables, expression levels and copy number variations of a number of relevant genes may be used to support assessment of malignant melanoma prognosis.

Iako je većina pigmentiranih promjena na koži (madeža, mrljica i sl.) dobroćudne naravi, ipak ih je sve potrebno pratiti kroz vrijeme, osobito one koje su novonastale ili se izgledom izdvajaju od drugih, okolnih promjena na koži. Na neke znakove treba osobito pripaziti, a u tome vam može pomoći akronim ABCDE. Svako slovo ove skraćenice označava karakteristiku kožne promjene na koju treba obratiti pažnju prilikom samopregleda:
