Lung cancer is one of the most feared forms of cancer, which develops silently without any symptoms until reaching its advanced stage. Cancer cells break off from the tumour spreading either through the lymphatic channel or bloodstream known as metastasis.
The cancer form spreads through the lymphatic channels and portions such as spleen and bone. Adrenal glands, liver and brain are the other areas to which the lung cancer may spread. Thereafter, cancer cells seek unaffected blood vessels and get attached to the body's blood and nutrient supply to cause further damage.
