Cancer detected after prolonged cough, unusual weight loss

Ms. TNC (60 years old, Hanoi ) has had a cough with phlegm for the past 2 weeks, accompanied by a rapid weight loss of 8kg in just 2 months. However, because she subjectively thought that the cough was a common respiratory disease, Ms. C. did not go to the doctor but waited until her regular health check-up to get checked.

At the medical facility, she was assigned to perform a full range of tests and paraclinical tests. Thyroid ultrasound results showed nodular thyroid enlargement in both lobes, accompanied by multiple bilateral cervical lymph nodes with atypical features of inflammation. Abdominal ultrasound detected some additional lymph nodes around the celiac artery.

In particular, the image from MSCT of the lungs and chest (without contrast injection) recorded chronic bronchitis on both sides of the lungs, the appearance of a mass of tissue outside the left lung lobe with a very high level of suspicion of malignancy. At the same time, a small opaque nodule was detected in the middle lobe of the right lung, suspected to be a secondary lesion.

Based on these signs, doctors diagnosed metastatic lung cancer. Ms. C. has been transferred to Military Hospital 175 for further treatment.

Dr. Bui Thi Cam Binh, an internal medicine specialist, shared that Ms. C's case warns against being subjective with symptoms such as prolonged cough and unexplained weight loss. Waiting until a routine check-up to get checked has caused the disease to progress to the stage of suspected metastasis, significantly reducing the chance of a complete cure.

"Everyone should proactively go see a doctor when they have any unusual symptoms that last for a long time, especially symptoms of unknown cause such as cough, weight loss, and prolonged fatigue," Dr. Binh recommends.
