Early Preterm Delivery And Breast Cancer

This is the only argument I found to be entirely false and, therefore, unacceptable. Several studies have debunked this theory time and time again. In fact, statistically speaking, a woman is technically at an increased risk for breast cancer after completing a term pregnancy

4. What are the hormonal and physical changes going on in Amber during her pregnancy? What is keeping her from menstruating as normal?

24) Prior to the onset of lactation, the mammary glands are prepared for the production of milk by

The reason is that when estrogen levels are lower during lactation, there’s a less riskless risk of these tissues becoming cancerous. The longer the mother breastfeeds, the lower the risk of developing breast cancer. Mother’s that bottle-feed formula are exposed to higher levels of estrogen since they don’t breastfeed and areand are at higher risk of developing ovarian and uterine cancers. Furthermore breastfeeding lessens the risk of developing osteoporosis as well. theyThey also have a greater chance of developing osteoporosis than breastfeeding women and are more likely to suffer from hip fractures in the post-menopausal years.

This paper aims to provide the gaps in our understanding of breast cancer by examining the functions and to enhance our ability to distinguish the anatomy of female human breast. The author also attempts a better understanding of some of the different types of human breast cancer namely: ductal carcinoma in situ, lobular carcinoma in situ, invasive ductal carcinoma and invasive lobular carcinoma. It is hoped that this paper will inform those who do not have the understanding and knowledge about the risk factors, diagnosis, treatments and preventions of the breast cancer.

The breasts are essentially a milk factory. Inside the breasts there are glands called lobules that are responsible for producing the milk. These glands contain branches of little sacs that hold the milk called alveoli. The lobules are positioned around ducts that carry milk to the nipple. Also, a layer of fatty tissue surrounds

The relationship between maternal smoking and fetal development shows that smoking raises the risk of early miscarriage and stillbirth. In the early stages of fetal development, cigarette smoke may cause genetic damage to the unborn baby. Smoking can change the lining of the uterus making it harder for the implantation of the fertilized egg. The dangerous chemicals found in cigarettes can cause a mother’s placenta to separate from the womb at a premature time. Smoking later in pregnancy appears to decrease the placenta’s ability to deliver nutrients to a developing baby. Some evidence even indicates that heavy smoking by

Breast cancer is a popular disease that many people are afraid of. It is the growth of altered genes that create malignant tumors starting in a female or male’s breast tissue. Cancer has a reputation of being caused by hormones, but that may not always be the case. Hormones are chemicals that work as chemical messengers in the body and affect the duties of cells and tissues. The ovaries in premenopausal and postmenopausal women usually produce the hormones, like estrogen and progesterone. The hormone estrogen develops and maintains the female sex features and progesterone have to do with women 's menstrual cycle and pregnancy. In a breast cancer cell, it

Breast caner appears in the milk-producing glands of the breast tissue. Groups of glands in normal breast tissue are called lobules. The products of these glands are secreted into a

The effects interact depending on a woman's age, and that is the increase in short-term risk and it lowers long-term risk. When a woman has her first child at age 35 or younger, she tends to get a protective benefit from pregnancy. The likelihood of breast cancer increased for about ten years after the first birth then it drops below the risk for the women who don't have any children (Ww5.komen.org, 2015). Women who have children at a later age are increasing their likelihood of breast cancer compared to women who have their first child at a younger age. The chance of having genetic damage goes up with age, and this is why women who have children at a later age have a higher risk of breast cancer than those younger. Breast cells grow during pregnancy, so if there is any genetic damage, the cells can copy and lead to breast cancer (Ww5.komen.org,

Such findings, all of which relate to hormone-based life events, suggest that breast cancer is somehow affected by prolonged exposure to female sex hormones, such as estrogen. Women with a history of breast cancer in the family are also at greater risk. About five percent of all breast cancers have been attributed to a mutated, or structurally altered, gene known as BRCA1. Mutations in a second gene, BRCA2, contribute significantly to the development of breast cancer in Jewish women. Alcohol, high levels of fat in the diet, and not exercising regularly have also been linked to increased risk for breast cancer (Garber).

A female breast consists of fatty and fibrous connective tissues. The interior of the breast is divided into about twenty different sections called lobes. Each of the lobes is further divided in to lobules, which are structures that contain small milk-producing glands. These glands place the milk into tiny ducts. These ducts take the milk through out the breast and store in a chamber located below the nipple.

Anderson then goes on to talk about the timing of abortion relative to childbirth, and explains that someone who has had a full term pregnancy prior to an abortion does not greatly increase her risk of developing breast cancer, since she has mature Type 3 and 4 lobules. The article moves on and briefly mentions the potential risk factors between IA and premature deliveries, and then explains the dose-effect between abortion and breast cancer. It is important to note that for every IA a woman has, she increases her risk of breast cancer because her immature lobules continue to multiply as they are exposed to estrogen. Anderson then notes that a 2013 meta-analysis of 36 studies revealed a significant increase in the risk of developing breast cancer, 1.44 (44 percent) increase

As a human infant undergoes development after birth, the breast undergoes involution post influences of maternal hormones. During puberty, stromal elements undergo growth and ramification of ductal tree and lobe formation enlarges the breast167. Based on menstrual cycle, the female breast undergoes cyclical changes during

Development of the mammary gland starts during embryogenesis but takes several years to complete; indeed, they are still primitive structures that are not yet connected to the nipple, therefore are not functional at birth (Anderson and Clarke). Until puberty, breasts grow extremely slow in size. However, at puberty, they undergo their first spurt of allometric growth and formation of the milk-producing lobules. The lobules extend into the mammary fat pad, and glands become more complex. During each menstrual cycle, ovarian hormones induce mammary development and new budding of structures up until the age of
