Ovarian cancer : Ovarian cancer is when cancer forms from the ovary. It is due to the development of abnormal cells that have the ability to invade or spread to other parts of the body.
Signs and symptoms of ovarian cancer are frequently absent in early stages. In most cases, the symptoms persist for several months before being recognized and diagnosed. Most typical symptoms include: bloating, abdominal or pelvic pain, difficulty eating, and possibly urinary symptoms. Other symptoms include an abdominal mass, back pain, constipation, tiredness and a range of other non-specific symptoms, as well as more specific symptoms such as abnormal vaginal bleeding or involuntary weight loss. There may be a build-up of fluid (ascites) in the abdominal cavity.
Lung cancer : Lung cancer, also known as carcinoma of the lung or pulmonary carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. If left untreated, this growth can spread beyond the lung by process of metastasis into nearby tissue or other parts of the body. Most cancers that start in the lung, known as primary lung cancers, are carcinomas that derive from epithelial cells. The main primary types are small-cell lung carcinoma (SCLC), and non-small-cell lung carcinoma (NSCLC). The most common symptoms are coughing (including coughing up blood), weight loss, shortness of breath, and chest pains.
Signs and symptoms which may suggest lung cancer include
• respiratory symptoms: coughing, coughing up blood, wheezing or shortness of breath
• systemic symptoms: weight loss, fever, clubbing of the fingernails, or fatigue
• symptoms due to the cancer mass pressing on adjacent structures: chest pain, bone pain, superior vena cava obstruction, difficulty swallowing
If the cancer grows in the airways, it may obstruct airflow, causing breathing difficulties. The obstruction can lead to accumulation of secretions behind the blockage, and predispose to pneumonia.
