In order to improve breast cancer outcomes and survival, early detection is critical. There are two early detection strategies for breast cancer: early diagnosis and screening. WHO Package of essential noncommunicable PEN disease interventions for primary health care in low-resource settings has guidance on the approach to assessment and referral for women with suspected breast cancer in the primary care setting. Screening consists of testing women to identify cancers before any symptoms appear. Various methods have been evaluated as breast cancer screening tools, including mammography, clinical breast exam and breast self-exam.

  • Cancer begins when cells in a part of the body start to grow out of control.

Our bodies are made of hundreds of different types of cells. And when processes inside them go wrong, and allow them to keep dividing uncontrollably, cancers form.

But individual cells are very small — by the time tumours which are made of millions of cells are large enough to be detected, the cells that make them up have evolved and changed along the way. A fascinating study from our researchers in Cambridge, published late last year , has begun to help answer these questions — at least for breast cancers.

The team, led by Dr John Stingl , traced the ancestry of different types of cell within normal, healthy breast tissue. And they found clues as to how these diverse cell types might be related to some of the different types of breast cancer.

The lobes and ducts are made of two layers of cells — called epithelial cells — which are a little like an undercoat and top layer of paint in your living room. And the surface layer of the milk lobes and ducts are made up of cells called luminal epithelial cells. But why are there so many different types? And, as any woman knows, over her life her breasts change quite significantly — first during puberty, then during pregnancy, and after childbirth to produce milk.

These are still relatively unspecialised and can divide like stem cells, but are further towards becoming a final luminal, milk-producing, or myoepithelial cell. Stem and progenitor cells have long been on the radar of scientists studying cancer. As these cells can carry on dividing forever, and cancer is a disease caused by uncontrolled cell division, they seem an obvious place to start looking for clues.

A couple of years ago, researchers led by Dr Matt Smalley made a surprising discovery. His lab, now based in Cardiff, was studying breast cancers that develop due to mistakes in the BRCA1 gene. And researchers naturally assumed that basal-like breast cancer originated from the basal myoepithelial cells.

But not all the evidence tied in with this. Scientists wanting to study breast progenitor cells have to isolate them from the rest of the cells in the breast. This method uses antibodies — small proteins made naturally by our bodies — to stick to pre-chosen proteins on the surface of human cells.

The scientists break down breast tissue into its constituent cells, and mix it with their antibodies so they stick to the cells of interest.

Finally, they pass the resulting mixture through a machine which pulls out each flag-bearing antibody and attached cell. Once isolated, they grew different cells in a laboratory to see whether they could divide and become milk duct cells i.

And these patterns were compared to the different types of breast cancers to look for similarities. There are, in fact, at least two different types of luminal progenitors in mice, some with, and some without, the oestrogen receptor. Similarly, when the team looked at breast tissue from humans, they also found two comparable groups of luminal progenitors, but with subtly different proteins on their surface.

However, the characteristics of these two groups of progenitor cells were similar in both mice and humans, and predicted whether the cells went on to become new luminal epithelial cells or milk-producing cells. One key finding was that a small group of progenitor cells those with high levels of the oestrogen receptor that become new luminal cells were better at surviving in conditions of low oestrogen. These seemed to be present in different levels in different tissue samples.

What they do, and how they relate to cancer, is still a complete mystery. This is important. Being able to tell the difference could mean that women with less aggressive tumours could be monitored and potentially avoid over-treatment. Tracing breast cancer back through its family tree to pinpoint the exact place and time it pops into existence is still a work in progress.

Gallen Oncology Conference in St. Gallen, Switzerland. Fenretinide , a retinoid, is also being studied as a way to reduce the risk of breast cancer retinoids are medications related to vitamin A. As of cryoablation is being studied to see if it could be a substitute for a lumpectomy in small cancers.

Part of the current knowledge on breast carcinomas is based on in vivo and in vitro studies performed with cell lines derived from breast cancers. These provide an unlimited source of homogenous self-replicating material, free of contaminating stromal cells, and often easily cultured in simple standard media.

The first breast cancer cell line described, BT , was established in Since then, and despite sustained work in this area, the number of permanent lines obtained has been strikingly low about Indeed, attempts to culture breast cancer cell lines from primary tumors have been largely unsuccessful.

This poor efficiency was often due to technical difficulties associated with the extraction of viable tumor cells from their surrounding stroma. Effusions provided generally large numbers of dissociated, viable tumor cells with little or no contamination by fibroblasts and other tumor stroma cells. Many of the currently used BCC lines were established in the late s. From Wikipedia, the free encyclopedia.

The explanation for these epidemiologic findings is not known, but the parallelism between the DMBA-induced rat mammary carcinoma model and the human situation is striking. Abortion would interrupt this process, leaving in the gland undifferentiated structures like those observed in the rat mammary gland, which could render the gland again susceptible to carcinogenesis.

Some of the earliest evidence of cancer is found among fossilized bone tumors, human mummies in ancient Egypt, and ancient manuscripts. Growths suggestive of the bone cancer called osteosarcoma have been seen in mummies. Bony skull destruction as seen in cancer of the head and neck has been found, too. Our oldest description of cancer although the word cancer was not used was discovered in Egypt and dates back to about BC.

It describes 8 cases of tumors or ulcers of the breast that were removed by cauterization with a tool called the fire drill. Galen AD , another Greek physician, used the word oncos Greek for swelling to describe tumors.

This mammogram, showing an abnormality in the breast, is the modern way to diagnose breast cancer. To the contrary: cancer has probably been around as long as humans. Skeletal remains of a 2, year old Russian King and a 2, year old Egyptian mummy have both been diagnosed with prostate cancers.

Breast cancer can also be traced right back to ancient Egypt, with the earliest recorded case described on the BC Edwin Smith Papyrus. Throughout the ages, nobody has really been sure what causes breast cancer. Research still continues today. Some of the earliest theories have long since fallen by the wayside.

The Ancient Greeks, for example, believed that imbalances of bodily humors fluids, especially black bile were responsible for breast cancer. But many other historic theories do still influence modern thought, with remnants of early beliefs left behind to form common breast cancer myths.

In the 17 th and 18 th centuries, lots of possible causes of breast cancer were suggested:. Early remedies for breast cancer were aimed at offering temporary relief or prolonging life rather than attempting to cure the disease.

Common treatments used throughout history when treating breast cancer include:. It now meant that breast cancer could be treated by isolating specific cells or removing affected areas; the beginning of the treatment known today as the mastectomy. These were the forerunners to the radical mastectomy, devised by William Halsted in the mid-nineteenth century. He agreed with the theory behind removal of the breasts and underlying areas for breast cancer patients but was very concerned about spreading the cancer cells further.

His contribution was a mastectomy which removed both breasts, lymph nodes and underlying muscles all in one piece. This became the standard breast cancer treatment until less radical, breast-sparing treatments began to be developed in the s. Maurer Foundation. A Brief History of Breast Cancer.
