Basal Cell Carcinoma

#basal cell carcinoma, #skin cancer, #ultraviolet rays, #skin, #tumor, #mole

Basal cell carcinoma is the most common skin cancer. It mainly occurs in areas with long-term ultraviolet exposure, and the outlook is generally favorable when it is completely removed by surgery. If you have an area of skin that has not healed for a long time or keeps changing, please be sure to consult a dermatologist.

Facial Flushing

#Facial flushing, #Flushing, #Rosacea, #UV exposure, #Vasodilation, #Face

Facial flushing is a condition in which blood vessels become abnormally widened (dilated), causing the facial skin to redden easily and the redness to persist. Summer heat and strong ultraviolet (UV) light can worsen symptoms. If symptoms persist or worsen, please see a dermatologist.

Heat Waves and Heart Health

Extreme heat raises the risk of angina, heart attack, and cardiac arrest by increasing heart rate, promoting blood clotting, and placing added strain on the heart. Older adults age 65 and older, people with cardiovascular disease, and those with chronic conditions such as high blood pressure or diabetes need to be especially careful. On days when a heat wave warning is issued, please stay active indoors for safety.

Macular Degeneration

#macular degeneration, #macula, #retina, #decreased vision, #eye injection, #dry macular degeneration, #wet macular degeneration, #lutein, #blurry vision, #difficulty seeing, #hazy vision

Macular degeneration is a condition in which the macula — the central part of the retina — is damaged, leading to decreased vision. In severe cases it can lead to blindness, but early detection and consistent treatment can help slow its progression. If you are 50 or older, please have regular retinal examinations.

Malignant Melanoma

#malignant melanoma, #melanoma, #skin cancer, #melanin, #skin, #mole, #pigment

Malignant melanoma is a malignant tumor that develops from melanocytes in the skin or mucous membranes. Melanocytes are the cells that produce skin pigment. Its prognosis tends to be the poorest among skin cancers, so early detection is very important. If you notice any unusual change in your skin, please be sure to consult a dermatologist.

Skin Aging

#skin aging, #photoaging, #wrinkles, #ultraviolet radiation, #aged skin, #dry skin, #hyperpigmentation

Skin aging refers to changes that occur in the skin over time, including wrinkles, reduced elasticity, and pigmentation changes. Sun protection and consistent skin care can help slow this process. If any new abnormality appears on the skin, please consult a medical specialist.

Skin Cancer

Skin cancer is a malignant tumor that develops in the skin. A malignant tumor is an abnormal mass of cells that harms the body. In its early stages, it may cause no symptoms or may resemble an ordinary mole or age spot. If you notice any unusual changes, please consult a dermatology specialist.

Squamous Cell Carcinoma

Squamous cell carcinoma is the second most common type of skin cancer. Ultraviolet (UV) exposure is the main risk factor, and it is more likely to recur and metastasize than basal cell carcinoma. If you notice any unusual changes in your skin, please consult a dermatology specialist.
