It is characterized as any change or aggravation to nature’s turf seen to be pernicious or undesirable. Ecological effect or degradation is created by the consolidation of an effectively substantial and expanding human populace, constantly expanding monetary development or per capita fortune and the application of asset exhausting and polluting technology. It occurs when earth’s natural resources are depleted and environment is compromised in the form of extinction of species, pollution in air, water and soil, and rapid growth in population.

Lungh Cancer

Cancer occurs because of mutations in the genes responsible for cell multiplication and repair. The changes which a cell undergoes in the process of malignant transformation is a reflection of the sequential acquisition of these genetic alterations. This multi-step process is not an abrupt transition from normal to malignant, but may take over 20 years or more. The mutation of critical genes, including supressor genes, oncogenes and genes involved in DNA repair, leads to genetic instability and to progressive loss of differentiation. Tumours enlarge because cancer cells lack the ability to balance cell division by cell death (apoptosis) and by forming their own vascular system (angiogenesis) . The transformed cells lose their ability to interact with each other and exhibit uncontrolled growth, invade neighbouring tissues and eventually spread through the blood stream or the lymphatic system to distant organs.
