Why is the reaction more uncomfortable after the tumor shrinks after treatment of advanced lung cancer

If the condition of patients with advanced lung cancer improves after active treatment but the symptoms become more severe, it may be caused by the spread of cancer cells, side effects of drugs, disease progression, etc.

1. Cancer cell spread: Lung cancer is a relatively malignant primary lung tumor. When the patient's condition develops to the late stage, cancer cells may metastasize and spread, causing damage to various organs of the body and causing a series of uncomfortable symptoms. Even if treatment is carried out at this time, the condition may worsen. It is recommended that family members give patients more care and companionship, and actively cooperate with doctors in radiotherapy, chemotherapy and other treatment measures to control the development of the disease.

2. Drug side effects: In clinical practice, many drugs used to treat cancer will produce some adverse side effects, such as nausea, vomiting, diarrhea, fatigue and other symptoms. These side effects may affect the patient's appetite and nutritional status, leading to weight loss, anemia and other problems. In the process of using drugs, it is necessary to closely observe the changes in the patient's condition and the side effects of the drugs, and adjust the treatment plan in time.

3. Disease progression: Although treatment for advanced lung cancer can relieve symptoms and prolong survival, it cannot cure the disease. As the disease progresses, cancer cells will continue to spread and invade surrounding tissues and organs, causing the disease to deteriorate further. Lung cancer may also cause worsening symptoms such as dyspnea, chest pain, cough, sputum, and hemoptysis. While receiving treatment, patients with advanced lung cancer also need to maintain a good attitude and eating habits to improve their quality of life and slow down the progression of the disease.

In addition, it may also be caused by psychological factors. It is recommended that family members give patients more care and support to help them build confidence in defeating the disease. At the same time, they should go to the hospital for regular check-ups and pay attention to changes in the condition at any time.
