If Kidney Cancer spreads to the lungs, what are the symptoms?

Renal cell carcinoma, also known by a gurnistical tumor, is the most common form of kidney cancer arising from the renal tubule. It is the most common type of kidney cancer in adults. Initial therapy is with surgery. It is notoriously resistant to radiation therapy and chemotherapy, although some cases respond to immunotherapy. Subsequently to be followed with Chemotheraphy and radiation theraphy to ensure no recurrance or spreading of the disease.

The outcome varies depending on the size of the tumor, whether it is confined to the kidney or not, and the presence or absence of metastatic spread. The Furhman grading, which measures the aggressiveness of the tumor, may also affect survival, though the data is not as strong to support this. inspite of all these treatments it may spread to Lungs and in which case it is very dangerous.

If it spreads to Lung and turn to be lung cancer the following sympoms can be seen.
Symptoms that suggest lung cancer include:

-dyspnea (shortness of breath)
-hemoptysis (coughing up blood)
-chronic cough or change in regular coughing pattern
-wheezing
-chest pain or pain in the abdomen
-cachexia (weight loss), fatigue and loss of appetite
-dysphonia (hoarse voice)
-clubbing of the fingernails (uncommon)
-difficulty swallowing

If the cancer grows into the lumen it may obstruct the airway, causing breathing difficulties. This can lead to accumulation of secretions behind the blockage, predisposing the patient to pneumonia.

Many lung cancers have a rich blood supply. The surface of the cancer may be fragile, leading to bleeding from the cancer into the airway. This blood may subsequently be coughed up.
In many patients, the cancer has already spread beyond the original site by the time they have symptoms and seek medical attention. Common sites of metastasis include the bone, such as the spine (causing back pain and occasionally spinal cord compression) and the brain.

If it spreads it is going to be a very difficult proposition and only your Oncologist can advise for further treatments a man on the spot.

So CANCER IS STILL AN ENIGME - Fight it.

Sometimes a cough but one may have no symptoms at all.

The ones I have seen experienced severe SOB.

At first there may not be any, as it progresses, it may cause shortness of breath, dizziness, pain, etc. It would be no different than regular lung cancer!
