Clinical Causes: Prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds Fair skin that is more susceptible to sun damage Older age, as skin cancer risks increase over time Exposure to carcinogenic substances such as arsenic History of skin cancer or precancerous skin lesions Weakened immune system, which impairs the body's ability to fight abnormal cell growth Chronic skin injuries or scars that may predispose to cancer development Genetic factors that increase susceptibility to skin cancers

Key Symptoms: New growth or a sore that does not heal A bump or nodule on the nose that persists or enlarges A red or translucent bump that may bleed or crust over Unusual pigmented areas or sores that change in size, shape, or color Scaly or crusted patches on the skin of the nose Persistent pain or tenderness in a localized area Indented or ulcerated areas on the skin of the nose Appearance of a shiny or pearly bump

Diagnosis Path: Diagnosis typically involves a physical examination of the nasal skin, where a healthcare provider assesses any suspicious lesions or masses. To confirm the presence and type of malignancy, a skin biopsy is performed, wherein a small sample of tissue is taken for microscopic analysis. Additional imaging tests like ultrasound, CT scans, or MRI may be utilized to determine the tumor's extent and whether it has invaded nearby tissues. Accurate diagnosis is crucial for planning appropriate treatment strategies.

Treatment Protocols: Surgical removal: Excisional surgery or Mohs micrographic surgery to precisely remove the tumor while sparing healthy tissue Radiation therapy: Used either alone or in conjunction with surgery for tumors not suitable for surgical removal Electrosurgery or curettage: Removing superficial lesions, often combined with topical treatments Topical therapies: Application of creams such as imiquimod or fluorouracil for superficial cancers Systemic therapy: In advanced cases, options like chemotherapy or targeted therapy may be considered
