Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.

Colon Cancer (Colorectal Cancer) is a malignancy that arises from the inner lining of the colon. Most, if not all, of these cancers, develop from colonic polyps. Removal of these precancerous polyps can prevent colon cancer.

Read about prostate cancer symptoms, treatment, survival rates, stages, surgery, screening, causes and diagnosis. Learn lifestyle strategies to reduce the risk of prostate cancer.

Pancreatic cancer is a malignant tumor of the pancreas. Pancreatic cancer has been called a "silent" disease because early pancreatic cancer usually does not cause early symptoms. Typically, pancreatic cancer has metastasized (spread to adjacent organs, such as the liver) by the time most people receive a dignosis of pancreatic cancer. Symptoms and signs usually appear later in the course of the disease and include jaundice, back pain, nausea, weight loss, itching, and loss of appetite. Treatment depends upon the type of pancreatic cancer but may include surgery, chemotherapy, and/or radiation therapy.

Lung cancer kills more men and women than any other form of cancer. Eight out of 10 lung cancers are due to tobacco smoke. Lung cancers are classified as either small-cell or non-small-cell lung cancers.

Breast cancer is an invasive tumor that develops in the mammary gland. Breast cancer is detected via mammograms, breast self-examination (BSE), biopsy, and specialized testing on breast cancer tissue. Treatment of breast cancer may involve surgery, radiation, hormone therapy, chemotherapy, and targeted therapy. Breast cancer risk may be lowered by managing controllable risk factors.

Treatment for bladder cancer depends on the stage of the disease, the grade of the tumor, and the type of bladder cancer. Options for treatment include surgery, radiation therapy, chemotherapy, and biological therapy.

Liver cancer is cancer of the liver cells (hepatocellular carcinoma) or of the ducts in the liver (cholangiocarcinoma). Liver cancer often arises due to liver damage, cirrhosis (scarring) caused by alcohol use/abuse, hepatitis B, or hepatitis C. Liver cancer may not cause any symptoms. Liver cancer is diagnosed with blood tests, imaging tests, and a liver biopsy. Treatment for liver cancer may include surgery, ablation, embolization, radiation, chemotherapy, and targeted therapy.

The goal of pain management for each patient is to minimize suffering and improve quality of life. This goal may be different depending on the patient’s circumstances and disease or injury.

Stomach cancer, also known as gastric cancer, develops in the lining of the stomach. Stomach cancer tends to develop slowly over many years.

Gastroparesis is a medical condition in which the muscle of the stomach is paralyzed by a disease of either the stomach muscle itself or the nerves controlling the muscle. As a consequence, food and secretions do not empty normally from the stomach. Gastroparesis symptoms are nausea and vomiting; abdominal bloating, and pain can result.

There are a variety of options that may help you handle your situation. It might help you to visualize each option and decide how you feel about it. Consider reaching out to trained professionals or close friends if you get overwhelmed.

Colon cancer is cancer of the last part of the large intestine. Colon cancer pain is generally felt as vague abdominal pain or cramps.

Cancers that form from brain tissue are called primary brain tumors. Brain tumors may be malignant (brain cancer) or benign. Certain risk factors, such as working in an oil refinery, as a chemist, or embalmer, increase the likelihood of developing brain cancer. Symptoms include headaches, weakness, seizures, difficulty walking, blurry vision, nausea,vomiting, and changes in speech, memory, or personality. Treatment may involve surgery, radiation therapy, or chemotherapy.

There are many types of ovarian cancer, epithelial carcinoma is the most common. Women with a family history of ovarian cancer have an increased risk of developing the disease. Some ovarian cancer symptoms include abdominal pain, nausea, diarrhea, constipation, and abnormal vaginal bleeding, however, they usually do not present until the disease has progressed. Early diagnosis is important for successful treatment.

Patients suffering from advanced kidney cancer may usually complain of back pain, which may be described as a dull ache to a sharp stabbing pain below the ribs on the back or one side of the flank. If there is a sudden persistent pain that lasts more than a few days, a doctor visit is recommended to rule out kidney cancer.

Symptoms and signs of cancer of the larynx, the organ at the front of the neck, include hoarseness, a lump in the neck, sore throat, cough, problems breathing, bad breath, earache, and weight loss. Treatment for larynx cancer depends on the stage (the extent) of the disease. Radiation therapy, surgery, and chemotherapy are all forms of treatment for laryngeal cancer.

The shoulder is the most often dislocated joint in the body due to its mobility. A dislocated shoulder occurs when the head of the humerus is dislocated from its socket. Symptoms of a shoulder dislocation include nausea and vomiting, lightheadedness, weakness, and sweating. There are various methods of reducing a dislocation and returning the humeral head to its normal place.

Patients with uterine cancer may complain of moderate-to-severe pain in their pelvic region. The pain usually radiates to their abdomen as well as chest as cancer grows. However, pain in the pelvic region may develop only in the later stages of uterine cancer. In more than 90 percent of women, unexpected abnormal vaginal bleeding is the most common early sign of ovarian cancer.

Cervical cancer is cancer of the entrance to the womb (uterus) caused by the human papillomavirus (HPV). Regular pelvic exams, Pap testing, and screening can detect precancerous changes in the cervix. Cervical cancer can be prevented by a vaccine. The most common signs and symptoms are an increase in vaginal discharge, painful sex, and postmenopausal bleeding. The prognosis and survival rate depend upon the stage at which the cancer was diagnosed.

Bone cancer is a rare type of cancer that occurs in cells that make up the bones. Primary bone cancer that arises in bone cells is different than metastatic bone cancer, which is cancer that arises in another part of the body and then spreads to the bones. Hereditary and environmental factors likely contribute to the risk of bone cancer. Signs and symptoms of bone cancer may include pain, the presence of a mass or lump, and bone fractures. There are different types of bone cancer (osteosarcoma, chondrosarcoma, Ewing's sarcoma, pleomorphic sarcoma, fibrosarcoma). Treatment for bone cancer may include surgical removal of the tumor, chemotherapy, radiation, and/or a stem cell transplant. The prognosis for bone cancer depends on the type of cancer and the extent of spread.

Anal cancer, cancer located at the end of the large intestine, has symptoms that include anal or rectal bleeding, anal pain or pressure, anal discharge or itching, a change in bowel movements, and/or a lump in the anal region. Treatment for anal cancer may involve radiation, chemotherapy, or surgery and depends upon the stage of the cancer, its location, whether cancer is eradicated after the first treatment, and whether the patient has HIV.Anal cancer is usually curable when found localized. Early detection remains the key to long-term survival as it is in many forms of cancer.

Read about inflammatory breast cancer rash, survival rates, treatment, and diagnosis. Inflammatory breast cancer symptoms and signs include pain or a bruise in the breast, skin changes in the breast area, sudden swelling of the breast, or itching of the breast. Learn more about prognosis, treatments, and diagnosis.

OxyContin and oxycodone are both pain-relieving prescription medications, or analgesics, that belong to opioid or narcotic drugs. Opioids are extracted from the poppy plant or its synthetic derivatives. Although opioids play a significant role in medicine in managing acute and chronic pain, they have a high potential of being abused.
