Types of breast cancers

There are several types of breast cancer, although some of them are quite rare. In some cases a single breast tumor can have a combination of these types or have a mixture of invasive and in situ cancer.

Ductal carcinoma in situ

Ductal carcinoma in situ (DCIS; also known as intraductal carcinoma) is the most common type of non-invasive breast cancer. DCIS means that the cancer cells are inside the ducts but have not spread through the walls of the ducts into the surrounding breast tissue.

About 1 in 5 new breast cancer cases will be DCIS. Nearly all women diagnosed at this early stage of breast cancer can be cured. A mammogram is often the best way to find DCIS early.

When DCIS is diagnosed, the pathologist (a doctor specializing in diagnosing disease from tissue samples) will look for areas of dead or dying cancer cells, called tumor necrosis, within the tissue sample. If necrosis is present, the tumor is likely to be more aggressive. The term comedocarcinoma is often used to describe DCIS with necrosis.

Lobular carcinoma in situ

Although it is not a true cancer, lobular carcinoma in situ (LCIS; also called lobular neoplasia) is sometimes classified as a type of non-invasive breast cancer, which is why it is included here. It begins in the milk-producing glands but does not grow through the wall of the lobules.

Most breast cancer specialists think that LCIS itself does not become an invasive cancer very often, but women with this condition do have a higher risk of developing an invasive breast cancer in the same breast or in the opposite breast. For this reason, women with LCIS should make sure they have regular mammograms and doctor visits.

Invasive (or infiltrating) ductal carcinoma

This is the most common type of breast cancer. Invasive (or infiltrating) ductal carcinoma (IDC) starts in a milk passage (duct) of the breast, breaks through the wall of the duct, and grows into the fatty tissue of the breast. At this point, it may be able to spread (metastasize) to other parts of the body through the lymphatic system and bloodstream. About 8 of 10 invasive breast cancers are infiltrating ductal carcinomas.

Invasive (or infiltrating) lobular carcinoma

Invasive lobular carcinoma (ILC) starts in the milk-producing glands (lobules). Like IDC, it can spread (metastasize) to other parts of the body. About 1 out of 10 invasive breast cancers is an ILC. Invasive lobular carcinoma may be harder to detect by a mammogram than invasive ductal carcinoma.

Less common types of breast cancer

Inflammatory breast cancer: This uncommon type of invasive breast cancer accounts for about 1% to 3% of all breast cancers. Usually there is no single lump or tumor. Instead, inflammatory breast cancer (IBC) makes the skin of the breast look red and feel warm. It also gives the breast skin a thick, pitted appearance that looks a lot like an orange peel. Doctors now know that these changes are not caused by inflammation or infection, but by cancer cells blocking lymph vessels in the skin. The affected breast may become larger or firmer, tender, or itchy. In its early stages, inflammatory breast cancer is often mistaken for an infection in the breast (called mastitis). Often this cancer is first treated as an infection with antibiotics. If the symptoms are caused by cancer, they will not improve, and the skin may be biopsied to look for cancer cells. Because there is no actual lump, it may not show up on a mammogram, which may make it even harder to find it early. This type of breast cancer tends to have a higher chance of spreading and a worse outlook than typical invasive ductal or lobular 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:

What are the symptoms of lymphoma?

Cancer symptoms are quite varied and depend on where the cancer is located, where it has spread, and how big the tumor is. Lymphoma usually first presents with swelling in the neck, underarm, or groin. Additional swelling may occur where other lymph nodes are located such as in the spleen. In general, enlarged lymph nodes can encroach on the space of blood vessels, nerves, or the stomach, leading to swollen arms and legs, to tingling and numbness, or to feelings of being full, respectively.
Lymphoma symptoms also include nonspecific symptoms such as fever, chills, unexplained weight loss, night sweats, lethargy, and itching
