Metastasis

WHAT IS METASTASIS?

Metastasis, also called secondary cancer, means spread of cancer from one organ to another distant organ. Pleural of metastasis is metastases. The original cancer is called primary cancer. This spread occurs either by blood or by lymph.

WHAT IS PULMONARY METASTASIS?

Pulmo is Latin word for lungs. When cancer spreads to one or both lungs, patient is declared as having pulmonary metastasis. They usually vary in size from rice grain to cricket ball and in number from one to more than a hundred. They are found as nodules or tumours within the lung tissue. They appear as bright white spots on chest x-ray and CT scan.30% of all cancer patients develop pulmonary metastasis. In 20%, lung is the only site of metastasis.  

COMMON SITES OF PRIMARY CANCER FROM WHERE PULMONARY METASTSIS ARISE

Cancers of rectum and colon, kidney, breast, prostate, uterus, cervix, bladder spread to lungs. Soft tissue sarcomas, osteosarcoma, germ-cell tumours, neuroblastoma , paediatric cancers and melanoma also throw metastasis to lungs.  

SYMPTOMS OF PULMONARY METASTSIS

80% of lung metastases are without any symptoms. Some patients may have cough, bloody sputum, wheezing, and loss of appetite, weight loss, easy fatigability, weakness or pain in chest, arm or shoulder. LAPM is not to treat any symptom but to remove the secondary cancer disease from lung.

If metastatic disease in lung grows unchecked, it can cause death by overwhelming the breathing capacity of lung, blocking major airways or invading vital structures like heart and major blood vessels around it.
