1, smoking. The common cause of lip cancer is long-term heavy smoking. Long-term heavy smoking will stimulate the oral mucosa and make it white over time. This is a smoke stain and can't be erased. Medical students call it hyperkeratosis, and long-term hyperkeratosis is likely to cause lip cancer, which is a signal of precancerous lesions.
2. Long-term outdoor work. Workers who work outdoors for a long time absorb a lot of sunlight for a long time. For some people, their lips may be congested and edematous, and their skin may get sunburned. Under normal circumstances, the lesions in the red lip area should be treated in time, otherwise it is likely to develop into lip cancer.
3. It is relatively rare that lip cancer may occur in warts and other lesions. Lower lip cancer often metastasizes to submental and submandibular lymph nodes; Upper lip cancer metastasized to preauricular, submandibular and cervical lymph nodes. Metastasis of upper lip cancer is earlier and more common than that of lower lip. The metastasis of lip cancer is generally less common than other oral cancers, and the metastasis time is later.
Clinical manifestations of lip cancer
1, lip symptoms
The initial symptoms are not obvious, but only limited hardening of bean grain size, which is easy to be ignored or misdiagnosed. After a long time, it grows gradually, like cocoon or nipple, hard and painful or bleeding, or local ulceration, uneven surface, uneven edge, cauliflower-like, or bayberry-like, fungus-like, and there is always dirty blood on the ulcer surface, and the surface is scabbed, which is difficult to heal after falling off.
Step 2: Pain
The early pain of lip cancer is intermittent and mild. With the deep infiltration of cancer cells into adjacent tissues and organs, the pain is aggravated and persistent.
3, dysfunction
Lip cancer often affects the mouth opening due to tumor swelling and pain, which hinders eating and talking. When the tumor destroys bone tissue, it can lead to tooth loosening, and when it invades mandibular joint, masticatory muscle, medial pterygoid muscle, temporal muscle and other muscle groups, it is difficult to open the mouth, which hinders the normal diet of patients.
4. Lymph node metastasis
Because of swallowing, chewing, language and other activities, cancer cells metastasized to submandibular, submental and deep cervical lymph nodes. When tumor cells invade the blood stream, they can metastasize far along the blood stream, especially in lung, liver and bone.
Treatment of lip cancer diseases
Early cases, whether surgery, radiotherapy, laser treatment or hypothermia treatment, have good curative effect; However, surgical treatment is suitable for advanced cases and cases with lymph node metastasis. For lip cancer without clinical metastasis, selective unilateral or bilateral suprascapulohyoid neck lymph node dissection is also feasible, but if clinically diagnosed with metastasis, neck lymph node dissection is needed. After resection of the primary lesion, the adjacent tissue flap can be used for immediate repair.
Is lip cancer fatal?
Lip cancer is a kind of cancer disease, and the consequences of cancer disease are more severe. When lip cancer occurs, people's physical function will be damaged. The mortality rate of this kind of cancer is relatively small, and it usually leads to death when it develops to the late stage.
How to prevent lip cancer
1, pay attention to the cleaning of lips.
People must take good care of their lips in life, especially in winter, when they are easy to dry. Remember to moisten your lips with some lip balm.
2. Keep a good attitude.
Everyone must form a good attitude and a positive and optimistic attitude towards life in life, which will help to prevent diseases better.
