Head and neck cancer is a general term for malignant tumors that develop in the head and neck region, including the larynx, oral cavity, oropharynx, hypopharynx, nasal cavity, and nasopharynx. Because this area is involved in essential everyday functions such as breathing, swallowing, and speaking, treatment can be challenging. If you have a voice change lasting more than 6 weeks, a mouth sore that doesn't heal after 3 weeks, or a lump in the neck, please see an ENT (ear, nose, and throat) specialist.

#lower extremity arterial disease, #peripheral arterial disease, #peripheral vascular disease, #leg pain, #atherosclerosis, #limb ischemia, #diabetic foot, #numbness in the hands and feet, #arm numbness, #tingling in the legs

Lower extremity arterial disease occurs when the arteries supplying blood to the legs become narrowed or blocked, reducing blood flow and causing symptoms such as pain, numbness, and delayed wound healing. Delayed diagnosis can lead to serious complications, so please be sure to consult a medical specialist if you experience any unusual symptoms in your legs.

Radiation therapy is a treatment that uses high-energy radiation to damage the DNA of cancer cells, which stops their growth and ultimately destroys them. Some normal cells are also damaged, but they usually recover more quickly than cancer cells and may return to normal function after treatment ends.

It is common in Korea, with about 30,000 people diagnosed each year. In its early stages, it often causes no symptoms, which makes it hard to detect early. Regular upper endoscopy is very important for early detection. If you notice unusual symptoms or have concerns, please be sure to see a medical 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.
