Lung cancer treatment failure can cause lung cancer brain metastasis, so lung cancer patients must pay attention to observe the symptoms of lung cancer brain metastasis and take timely care measures after treatment failure. Let’s take a look at the knowledge about lung cancer metastasis. Symptoms of brain metastasis of lung cancer When it comes to brain metastasis of lung cancer, many people may not know about it. Therefore, they do not know what are the symptoms of lung cancer brain metastasis. 1.Headache The headache is more intense in nature and often occurs in the early morning, sometimes waking up from sleep with pain, but the headache will gradually ease or disappear after getting up and doing light activities. 2.Vomiting Due to the increase of intracranial pressure, the medulla oblongata respiratory center is stimulated, thus vomiting occurs, and vomiting mostly occurs after the headache, in the form of jets. 3.Visual impairment Patients suffering from brain metastasis of lung cancer will experience increased intracranial pressure, which will lead to bruising and edema that will injure the retina and eventually lead to vision loss. Brain tumors located in the frontal lobe of the brain may disrupt the mental activities of the frontal lobe, causing mental abnormalities such as excitement, agitation, depression, repression, forgetfulness, and fictitiousness. Unilateral limb sensory abnormalities or weakness The parietal lobe located in the middle of the cerebral hemisphere is specialized in sensory management. Tumors in this area often cause unilateral limb pain, temperature, vibration and shape discrimination sensation to be reduced or disappeared. 6.Phantom smell A tumor in the temporal lobe can cause phantom smell under its stimulation, i.e. smelling an odor that does not exist, such as burnt rice or burnt rubber. 7. Hemiplegia or staggering gait The cerebellar lesions are more specific, i.e. patients often develop hemiplegia or staggering drunken gait after headache, vomiting and visual impairment. 8. Tinnitus, deafness This kind of tinnitus is mostly found when talking on the phone, i.e., one ear can hear but the other ear cannot. Vitamin C is beneficial to lung cancer prevention and treatment Vitamin C is the most well-known nutrient, and there are many studies on it at home and abroad. The following people need to pay extra attention to vitamin C supplementation in their lives: smokers. Studies have found that because of its antioxidant and other effects, vitamin C can reduce the risk of cancer and respiratory obstructive disease from smoking by 50%, and because smokers need 40% more vitamin C than non-smokers, so older smokers must pay attention to supplementation. People with high psychological stress. Some studies show that when under strong psychological stress, the body consumes eight times more vitamin C than usual. For such people, vitamin C has the effect of balancing psychological stress. Women during the menstrual period. Women lose iron faster during this time of the year. Vitamin C can help absorb iron and prevent anemia. People with iron deficiency anemia can also take vitamin C supplements along with iron supplements. In addition, people who live in urban areas should take 2-3 times more vitamin C than others because carbon monoxide destroys vitamin C. People who work in hot environments can also take vitamin C supplements under the guidance of a doctor. It is worth reminding that some of the “subhealth” symptoms in daily life are probably due to vitamin C. The “symptoms” are likely to be the precursors of vitamin C deficiency, such as muscle pain, fatigue, tiredness, easy to catch a cold, gums easy to red and swollen, etc., under the guidance of a doctor to supplement vitamin C in the right amount, may receive good results. If the usual diet can not supplement enough vitamin C, you can take a moderate amount of supplements, generally 100 mg per day, not more than 1000 mg. Small doses taken several times, at least twice a day supplement, this is because, vitamin C in the human body can only stay about 4 hours, a supplement more easily wasted.
