from an abnormality in the body ’s basic unit of life‚ the cell. Tumors can also cause cancer. Tumors usually can be removed and do not spread to other parts of the body. Malignant tumors‚ on the other hand‚ grow aggressively and invade other tissues of the body‚ allowing entry of tumor cells into the bloodstream or lymphatic system and then to other sites in the body. This process of spread is termed metastasis; the areas of tumor growth at these distant sites are called metastases. Since lung cancer

in diagnosis. Some breast cancers are sensitive to hormones such as estrogen and/or progesterone‚ which makes it possible to treat them by blocking the effects of these hormones in the target tissues. Estrogen and progesterone receptor positive tumors have better prognosis and require less aggressive treatment than hormone negative cancers. Breast cancers without hormone receptors‚ or which have spread to the lymph nodes in the armpits‚ or which express certain genetic characteristics‚ are higher-risk

those changes should have her going to the doctor and have her concerned. 4. Considering the differences between a benign tumor and a malignant tumor‚ why might a benign tumor be easier to treat? (3 points) Cells in benign tumors do not spread to other parts of the body. Malignant tumors are cancerous and are made up of cells that grow out of control. Cells in these tumors can invade nearby tissues and spread to other parts of the body. 5. Judy learned that every single person has these cell cycle

cells in the breast‚ most commonly in the lining of the milk ducts or milk producing glands become abnormal and divide without control or order as a normal cell would. When cancer cells break away from the original tumor and enter the blood stream or the lymphatic system‚ secondary tumors may form‚ invading or damaging other parts of the body including vital organs. According to the World Health Organization about more than 1.2 million people are diagnosed with breast cancer a year worldwide. The

INTRODUCTION We define tumor as new abnormal growth of tissue. Normally after puberty our body stops growing‚ but tissue cells continue dividing in order to replace those cells that die of injury or old age. Sometimes an abnormal cell with capacity to divide out of control may arise. This cluster of abnormal cells then forms a tumor. A tumor is simply a swelling and does not necessarily imply cancer. If a tumor does not grow or only grows in its local area‚ it is called benign tumor. However‚ if it has
