What is Stage IV Cancer?
Before answering what is stage IV cancer, it is best to explain the four stages of cancer.
The stage of cancer describes the extent of metastases and is numbered I to IV. Staging takes into account the tumor size, penetration into the tissues or organs, invasion of adjacent organs, and metastases to distant body parts. Staging is important in the sense that it determines the survival rate of the patient and determines the treatment applicable to the cancer case.
Correct staging is critical because treatment directly relies on the disease stage. Therefore, incorrect staging leads to improper treatment, and false estimation of prognosis or survivability. It is however difficult to achieve correct staging. Pathologic staging may lead to false staging due to visual discretion and random sampling of tissue. Visual discretion refers to identification of single cancerous cells mixed with healthy cells on a slide. Random sampling refers to the fact that samples are cherry-picked from the patient’s affected body part. If cancerous cells present in the lymph node happen to be absent in the slices of tissue viewed, incorrect staging and improper treatment can result.
Overall Stage Grouping is named Roman Numeral Staging: Stage 0 carcinoma in situ; Stage I cancers are localized to one body part; Stage II cancers are locally advanced; Stage III cancers are also locally advanced (designation as Stage II or Stage III may depend on the specific type of cancer); and Stage IV cancers have metastasized to other organs or throughout the entire body.
What is stage IV cancer of the breast? Stage IV breast cancer is distant metastatic cancer where the cancer has spread to other parts of the body. In most cases of breast cancer, women under stage IV breast cancer undergo hormone therapy, chemotherapy, or both. Some may have biological therapy. Controlling tumors in certain body parts may be facilitated through radiation. These treatments do not aim to cure the disease but allow the woman to live longer. Supportive care along with anticancer treatments slows down the progress of the disease. Supportive care involves any treatment method used to manage pain, symptoms, or side effects of the disease or treatment. Supportive care does not aim to lengthen a woman’s live but helps her feel better physically and emotionally. Some cancer patients decide to have supportive care alone.
What is stage IV cancer of the lung? Stage IV lung cancer indicates spread of malignant tumors from the chest to other parts of the body, usually the liver, bones, or brain. Treatment for stage IV lung cancer is not aimed at giving cure to the disease. Instead, treatment options are done to slow down the effects of the disease, prolong survival, diminish symptoms, and maximize comfort. Patients with advanced stages of lung cancer are not provided the option for surgery as it may no longer remove the tumor that has metastasized. Chemotherapy is the primary form of treatment. It slows down growth of metastases. Other patients with a lesion in the lung or a metastasis in the brain may benefit from surgery but this condition is rare.
What is stage IV cancer of the colon? Stage IV colon cancer indicates spread to distant sites such as the liver, lung, peritoneum, or ovary. The goal of surgery in this stage is to relieve the colon and prevent other local complications. Extensive metastases may require management of the disease by inserting a tube through the tumor during colonoscopy to avoid surgery. Surgery in stage IV does not lead to cure. If few metastases are present in the liver and can be removed completely together with the colon cancer, surgery can prolong the life of the patient and may at rare times lead to cure of the disease. Chemotherapy may also be performed by directly injecting drugs into the arteries that lead to the liver. This shrinks the cancers in the liver more effectively than intravenous chemotherapy injections. The disadvantage of this is that it permits the cancer to metastasize in another part of the body. Thus, chemotherapy given directly to the liver does not usually prolong life any better than intravenous chemotherapy. If metastases cannot be surgically removed because of their size or quantity, freezing, heating with microwaves or other nonsurgical methods may be performed.
What is stage IV cancer of the prostate? Stage IV prostate cancers have already metastasized to the bladder, rectum, lymph nodes, or distant organs. Stage IV prostate cancers are generally considered not curable. Treatment options may include hormone therapy, external beam radiation and hormone therapy, surgery (TURP) to relieve symptoms like bleeding or blockage of the urinary tract, and watchful waiting for older men whose cancer does not reveal symptoms or for others who have other serious diseases or illnesses.
What is stage IV cancer of the skin? Palliative care is the usual treatment choice for people with stage IV skin cancer or melanoma. This is because tumor has spread to other places in the body like the brain or lung. The goal of palliative care is to make the patient feel better physically and emotionally. Therefore, the treatment is focused on controlling pain and regulating symptoms and to lessen or relieve the side effects of therapy. Surgery may be performed to remove lymph nodes that contain cancer cells or remove tumors that have metastasized to other parts of the body. Radiation therapy, biological therapy, or chemotherapy may be performed to relieve symptoms of the disease.
Cancer treatment teams help patients overcome stage IV cancer of any kind by empowering them to be active in the treatment process. Intergrative approaches to stage IV cancer treatments continue to evolve. Nutritionists, counselors, psychologists, oncologists, and physicians work together to provide support to cancer patients going through a difficult challenge in life. Cancer patients should receive comprehensive care – physically, emotionally, spiritually, and psychologically.
Many people suffering from stage IV cancer have found comfort in the treatment methods developed nowadays. It is important that the quality the lives of patients are improved through different medical and holistic activities. There are some stage IV cancer victims who have actually survived and who continue to tell their stories to help other cancer patients face the battle with cancer.
