Breast cancer is one of the most common invasive cancers in females that is also a leading cause of death in them. A lump or a mass in the breast is one of the first signs of breast cancer. In many cases, these lumps are painless. A person may experience pain in the ni**le or breast area that appears to be associated with their menstrual cycle. Breast cancer develops as a result of genetic mutations or damage to DNA.

Asthma is an inflammatory disease of the airways of the lungs. It can lead to difficulty in breathing and can make some physical activities difficult or even impossible for the patient. Asthma symptoms arise when the lining of your airways swells and the muscles around them compress. The mucus then fills the airways, further reducing the amount of air that can pass through. All this can lead to an asthma attack that results in tightening of the chest and coughing.
