Lung cancer is a malignant tumor that develops in the bronchi or lungs and is the leading cause of cancer death in Korea. It often causes no symptoms in its early stages, so regular screening is important for high-risk groups. Smoking is the leading cause, and quitting smoking is the most effective way to help prevent it.

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.

Thyroid Nodules and Thyroid Cancer

Thyroid cancer is a malignant tumor that develops in the thyroid gland, a butterfly-shaped endocrine organ at the front of the neck that secretes the thyroid hormones that regulate the body's metabolism. Thyroid nodules (lumps) are very common, and a portion of them are found to be cancer, so early detection through ultrasound and cytology is important. If you can feel a lump in your neck or have symptoms such as voice changes, please consult an ENT specialist.

Tongue Cancer

Tongue cancer is a malignant tumor that develops in the tongue and accounts for about 10 to 15% of all head and neck cancers. Because early symptoms resemble those of stomatitis (mouth sores), it is often left untreated and found late. Treatment outcomes tend to be better when the cancer is detected early, so if you have a sore on the tongue that does not heal or a lump you can feel, please consult a medical specialist without delay.
