Breast cancer -Surgery

Surgery is usually the first line of attack against breast cancer. This section explains the different types of breast cancer surgery. Decisions about surgery depend on many factors. You and your doctor will determine the kind of surgery that’s most appropriate for you based on the stage of the cancer, the "personality" of the cancer, and what is acceptable to you in terms of your long-term peace of mind. The following pages will help you explore your surgery options: * In our What to Expect with Any Surgery section, you can learn the basic steps common to all breast cancer surgeries. * If you need to choose between surgeries, Mastectomy vs. Lumpectomy explains the pros and cons of each. * Lumpectomy, also known as breast-conserving surgery, is the removal of only the tumor and a small amount of surrounding tissue. * Mastectomy is the removal of all of the breast tissue. Mastectomy is more refined and less intrusive than it used to be because in most cases, the muscles under the breast are no longer removed. * Lymph node removal, or axillary lymph node dissection, can take place during lumpectomy and mastectomy if the biopsy shows that breast cancer has spread outside the milk duct. Some people qualify for the less-invasive sentinel lymph node dissection. * Breast reconstruction is the rebuilding of the breast after mastectomy and sometimes lumpectomy. Reconstruction can take place at the same time as cancer-removing surgery, or months to years later. Some women decide not to have reconstruction and opt for a prosthesis instead. * Prophylactic mastectomy is preventive removal of the breast to lower the risk of breast cancer in high-risk people. * Prophylactic ovary removal is a preventive surgery that lowers the amount of estrogen in the body, making it harder for estrogen to stimulate the development of breast cancer.

What is the treatment for ovarian cancer?

Treatment for ovarian cancer consists of surgery, chemotherapy, a combination of surgery with chemotherapy, and sometimes radiotherapy. The kind of treatment depends on many factors, including the type of ovarian cancer, its stage and grade, as well as the general health of the patient.
Some studies have indicated that specialized hospitals tend to have better survival rates for ovarian cancer patients, compared to general hospitals

Surgery

The surgical removal of the cancer is performed in the vast majority of ovarian cancer cases, and is often the first treatment the patient will undergo.

Unless the ovarian cancer is very low grade, the patient will require an extensive operation that includes the removal of both ovaries, the fallopian tubes, the uterus, nearby lymph nodes, and the omentum (a fold of fatty abdominal tissue). Cancer often spreads into the omentum. In most cases the operation will be carried out by a gynecologic oncologist surgeon - a specialist in surgery for women with cancer of the reproductive organs. This operation, sometimes referred to as a total hysterectomy, will mean that the woman will begin her menopause immediately. Recent research by Canadian scientists found that premature removal of the ovaries increases the risk of lung cancer.

If the cancer is confined to just one of the ovaries the surgeon may just remove the affected ovary and the adjoining fallopian tube. The woman will have a chance of being able to conceive. If both ovaries are removed it will not be possible to conceive.

Surgery for ovarian cancer will require a hospital stay of up to two weeks, plus a recovery period of at least six weeks when the patient gets back home.

Chemotherapy

Chemotherapy is the use of chemicals (medication) to treat any disease - more specifically in this text, it refers to the destruction of cancer cells. Cytotoxic medication prevents cancer cells from dividing and growing. When health care professionals talk about chemotherapy today, they generally tend to refer more to cytotoxic medication than others. Chemotherapy for ovarian cancer, as well as most other cancers, is used to target cancer cells that surgery cannot or did not remove.

Patients will typically receive a combination of carboplatin (Paraplatin) and paclitaxel (Taxol) intravenously (injected into the bloodstream). As it is injected into the bloodstream it can target cancer cells in the reproductive system, as well as any cancer cells that may have reached elsewhere in the body.

Treatment usually involves 6 to 12 chemotherapy sessions which will be given three to four weeks apart so that the body has time to recover. One session usually consists of a 3-hour gradual injection of the medicine into the body; sometimes it may be extended to 24 hours. Extended injections require an overnight stay in hospital.

Radiotherapy

Radiation is not the mainstay of ovarian cancer treatment - it is not generally considered effective for ovarian cancer. It may be used if there are small traces of cancer in the reproductive system, or to treat the symptoms of advanced cancer. External radiotherapy may be used to clear traces of cancer left after chemotherapy, while internal radiotherapy may be used for advanced cancer. Radiotherapy may cause the following symptoms; some symptoms may not appear until a long time after treatment is over:

Lung cancer treatments

Lung cancer treatments depend on the type of cancer, the stage of the cancer (how much it has spread), age, health status, and additional personal characteristics. As there is usually no single treatment for cancer, patients often receive a combination of therapies and palliative care. The main lung cancer treatments are surgery, chemotherapy, and/or radiation. However, there also have been recent developments in the fields of immunotherapy, hormone therapy, and gene therapy.

Surgery

Surgery is the oldest known treatment for cancer. If a cancer is in stage I or II and has not metastasized, it is possible to completely cure a patient by surgically removing the tumor and the nearby lymph nodes. After the disease has spread, however, it is nearly impossible to remove all of the cancer cells.

Lung cancer surgery is performed by a specially trained thoracic surgeon. After removing the tumor and the surrounding margin of tissue, the margin is further studied to see if cancer cells are present. If no cancer is found in the tissue surrounding the tumor, it is considered a "negative margin." A "positive margin" may require the surgeon to remove more of the lung tissue.

Lung cancer surgery can be curative or palliative. Curative surgery aims to cure a patient with early stage lung cancer by removing all of the cancerous tissue. Palliative surgery aims to remove an obstruction or open an airway, making the patient more comfortable but not necessarily removing the cancer.

Surgery carries side effects - most notably pain and infection. Lung cancer surgery is an invasive procedure that can cause harm to the surrounding body parts. Doctors will usually provide several options for alleviating any pain from surgery. Antibiotics are commonly used to prevent infections that may occur at the site of the wound or elsewhere inside the body.

Radiation

Radiation treatment, also known as radiotherapy, destroys or shrinks lung cancer tumors by focusing high-energy rays on the cancer cells. This causes damage to the molecules that make up the cancer cells and leads them to commit suicide. Radiotherapy utilizes high-energy gamma-rays that are emitted from metals such as radium or high-energy x-rays that are created in a special machine. Radiation can be used as the main treatment for lung cancer, to kill remaining cells after surgery, or to kill cancer cells that have metastasized.

Early radiation treatments caused severe side-effects because the energy beams would damage normal, healthy tissue, but technologies have improved so that beams can be more accurately targeted. Radiation oncologists can focus the radiation in precise locations in the body for certain lengths of time, reducing the risk of damage to surrounding healthy tissue. Treatments occur intermittently over weeks or months depending on the size and extent of the tumor, the dosage of radiation, and how much damage is being done to noncancerous tissue.

Common side effects of radiation therapy include fatigue, nausea, loss of appetite, hair loss, and skin affectations that cause skin to become dry, irritated, and sensitive.

Chemotherapy

Chemotherapy utilizes strong chemicals that interfere with the cell division process - damaging proteins or DNA - so that cancer cells will commit suicide. These treatments target any rapidly dividing cells (not just cancer cells), but normal cells usually can recover from any chemical-induced damage while cancer cells cannot. Chemotherapy is considered systemic because its medicines travel throughout the entire body, killing the original tumor cells as well as cancer cells that have spread throughout the body.

A medical oncologist will usually prescribe chemotherapy drugs for lung cancer to be taken intravenously, but there are also drugs available in tablet, capsule, and liquid form. Chemotherapy treatment occurs in cycles so the body has time to heal between doses, and dosages are determined by the type of lung cancer, the type of drug, and how the person responds to treatment. Medicines may be administered daily, weekly, or monthly, and can continue for months or even years.

Combination therapies often include multiple types of chemotherapy, and chemotherapy is also given as adjuvant therapy as a complement to surgery and radiation. Adjuvant therapy is designed to reduce the risk of cancer recurrence after surgery and killing any cancer cells that exist after surgery. Chemotherapy can be given before surgery, called neo-adjuvant therapy, to shrink tumors and to make surgery more successful.

Chemotherapy carries several common side effects, but they depend on the type of chemotherapy and the health of the patient. These include nausea and vomiting, appetite loss, diarrhea, hair loss, fatigue from anemia, infections, bleeding, and mouth sores. Many of these side effects are only temporarily felt during treatment, and several drugs exist to help patients cope with the symptoms.

What Are The Pancreatic Cancer Treatment Options

Surgery

Surgery may be used to remove all or part of the pancreas. If a cancer has not metastasized, it is possible to completely cure a patient by surgically removing the cancer from the body. After the disease has spread, however, it is nearly impossible to remove all of the cancer cells.

Chemotherapy

Chemotherapy utilizes chemicals that interfere with the cell division process - damaging proteins or DNA - so that cancer cells will commit suicide. These treatments target any rapidly dividing cells (not necessarily just cancer cells), but normal cells can usually recover from any chemical-induced damage while cancer cells cannot. Chemotherapy is generally used to treat cancer that has spread or metastasized because the medicines travel throughout the entire body. Treatment occurs in cycles so the body has time to heal between doses. However, there are still common side effects such as hair loss, nausea, fatigue, and vomiting. Combination therapies often include multiple types of chemotherapy or chemotherapy combined with other treatment options.

Radiation

Radiation treatment, also known as radiotherapy, destroys cancer by focusing high-energy rays on the cancer cells. This causes damage to the molecules that make up the cancer cells and leads them to commit suicide. Radiotherapy utilizes high-energy gamma-rays that are emitted from metals such as radium or high-energy x-rays that are created in a special machine. Radiotherapy can be used as a standalone treatment to shrink a tumor or destroy cancer cells, and it is also used in combination with other cancer treatments.

Radiation treatments for pancreatic cancer are usually given 5 days a week for 5 to 6 weeks. Patients may receive radiation treatment in addition to surgery, chemotherapy, or other treatments. In addition, radiation therapy can be palliative, serving to relieve pain or digestive problems when the common bile duct or duodenum is blocked.
