Introduction
A mole that grows larger over time can be caused by natural growth, aging, ultraviolet radiation, hormonal changes, or congenital giant nevi. As people age, the skin's metabolism and pigment distribution may change, leading some moles to gradually enlarge. This is a natural phenomenon during the skin's aging process and can be treated through surgical removal.
Generally, the gradual enlargement of moles can be caused by natural growth, aging, ultraviolet radiation exposure, hormonal changes, or congenital giant moles. If discomfort occurs, timely medical consultation is recommended. Detailed explanations are as follows:
1. Natural Growth
Moles are benign pigmented clusters on the skin and may gradually enlarge during their development. This typically is a slow and stable process without accompanying abnormal symptoms. Laser mole removal can be used, whereby the laser emits high energy instantaneously onto the pigmented tissue, breaking down the pigment into fragments that are then phagocytized by macrophages and excreted from the body, achieving the purpose of pigment removal.
2. Aging
With increasing age, changes in skin metabolism and pigment distribution may cause certain moles to gradually enlarge. This is a natural phenomenon of skin aging. Surgical excision is an option.
3. Ultraviolet Radiation Exposure
Prolonged exposure to intense ultraviolet radiation can stimulate melanocytes, increasing melanin deposition and consequently causing moles to grow larger. Avoiding prolonged UV exposure and using sunscreen are recommended preventive measures.
4. Hormonal Changes
Hormonal fluctuations are often associated with stress and emotional excitement. Changes in hormone levels, especially increased estrogen levels, can stimulate melanocyte activity, leading to mole enlargement. Such moles typically have clear borders and uniform coloration and may present with symptoms such as pain or warmth. It is recommended to follow medical advice regarding the use of medications such as bicalutamide tablets, flutamide tablets, or abiraterone acetate tablets for treatment.
5. Congenital Giant Moles
Congenital giant moles are associated with abnormal genetic factors, resulting in excessive local proliferation of melanocytes, forming large moles that may be accompanied by multiple moles or skin pigmentation disorders. Patients should follow medical advice regarding the use of topical medications such as tretinoin cream, hydroquinone cream, or imiquimod cream for treatment.
It is recommended to maintain a positive and optimistic mindset, avoiding excessive anxiety and tension, which can help alleviate physical stress and skin-related issues.
