Evolve case study answers breast cancer

How do the ER and PR receptors work? This allowed small samples of tumour tissue to be removed from women with breast cancer and grown in the lab for a short time.

When breast cancer develops, the tumour cells become overly sensitive to oestrogen. According to Dr Carroll, this is precisely what needs to be done, and the next steps are obvious. Only certain types of cells that respond to hormones make these receptors — for example breast, ovary and womb cells.

Metastatic breast cancer case review

Apparently in recent years there has been much research completed looking for a solid answer to the question. But, most crucial part was the overall effect this on the cancer cells themselves — progesterone seemed to cause the cells to stop growing as quickly. Many contraceptives, and certain forms of HRT, contain derivatives of progesterone e. But when they gave the mice tamoxifen AND progesterone, the tumours grew even more slowly. Essentially, people are worried about their brains being microwave, breaking bonds and causing genetic damage and consequently a cancerous tumor to evolve. Whether or not someone answering their cell phone is increasing the likelihood of fatal brain cancer, is in question. In the past twenty years, there have been a few scientific advances, which have stood out among the rest. Cancer is described as an uncontrollable division of cells. If it is cancer, has it started spreading? This allowed small samples of tumour tissue to be removed from women with breast cancer and grown in the lab for a short time. Only certain types of cells that respond to hormones make these receptors — for example breast, ovary and womb cells. About 7 out of ten women have ER-positive breast cancer.

When oestrogen and progesterone are present, these hormones physically stick to their respective receptor, causing them to move into the nucleus of the cell, where DNA is housed.

Many contraceptives, and certain forms of HRT, contain derivatives of progesterone e.

Youngest documented case of breast cancer

Although in some cases these treatments are effective at removing tumors, they are not selective against cells within the tumor and are frequently toxic to the patient. But when they gave the mice tamoxifen AND progesterone, the tumours grew even more slowly. How is Melanoma caused? The first hint The first piece of the jigsaw fell into place when they looked at the physical relationship between the two receptors. The final, and most crucial, experiment was to see if their findings had any potential implications for treating breast cancer. This allowed small samples of tumour tissue to be removed from women with breast cancer and grown in the lab for a short time. Changing the way breast cancer is treated? This was a strong hint that progesterone — via the progesterone receptor — was somehow affecting how the oestrogen receptor works. Overview of Case and Pathophysiology 45 points Pathogenesis: The case study identifies a given disease.

And how aggressive it is likely to be? InLouis Pasteur decided to take on rabies. The second fact: Smoking is the most important reasons that lead to chronic lung disease and cancer.
