Is it serious to have fluid on review 3 weeks after surgery for stage 3a squamous lung cancer?

Fluid accumulation in 3 weeks after surgery for stage 3a squamous lung cancer may be caused by postoperative inflammatory reaction, lymphatic reflux obstruction or metastasis of cancer cells, etc. The severity of fluid accumulation caused by different reasons is different.
1. Postoperative inflammatory reaction: local tissue infection may be caused in the process of squamous lung cancer surgery, which is usually not serious after active anti-infection treatment, if the effusion is more, local puncture and fluid extraction should be carried out.
2. Obstruction of lymphatic reflux: stage 3a surgery for squamous lung cancer will carry out peripheral lymph node dissection according to the location of the tumor, and the lymphatic reflux will be somewhat obstructed after the surgery, which will lead to the occurrence of pleural effusion, a small amount of effusion usually does not need treatment, while a large amount of effusion should be treated under the guidance of the doctor and corresponding measures should be taken.
3. Cancer cell metastasis: if cancer cell metastasis occurs after surgery for stage 3a squamous lung cancer and metastasizes to the pleura, it will lead to pleural effusion, and further measures should be taken in time to slow down the progress of the disease. Such cases are serious.
It is recommended that postoperative lung cancer patients should have timely rechecks and seek medical treatment when pleural effusion is found, so that professional doctors can conduct further examination and take corresponding treatment measures according to the specific conditions of the patients.
