Question 1

why do humans have enlarged breasts when other mammals don't?

Accepted Answer

Excellent question: There has been much speculation and most points to evolution, if you are a believer. While most animals are quadriods and the buttocks is more attractive to most 4 legged animals, as we became upright, some evolution biologists believe the breasts are buttock analogiues when humans face each other. Larger breasts suggest greater health and reproductive capabilities and impart an advantage.

Question 2

production of milk in the breasts leading to a decline of the production of lactase. does human milk contain lactose?

Confusing question: The sugar of breast milk is lactose.

Question 4

is is dangeous to taste human breast milk?

Accepted Answer

Breast milk: No, but you may find it very sweet.

Question 5

what is the amount of vitamin k in human breast milk ?

Accepted Answer

Varies: Vit k is a fat soluble vitamin found in higher concentrations in colostrum, first milk letdown, i'm the first few days of lactation. After that, content lowers but still present. The committee on nutrition of the american academy of pediatrics has recommended 0.5-1.0 mg vit k1 be administered to all newborns shortly after birth to help with newborn vit k levels. Breastfeeding always recommended.

Question 6

describe microrna gene expression deregulation in human breast cancer?

Accepted Answer

Can't do in 400: The study of micro-rnas is cutting-edge and extremely arcane and you need to go directly to pubmed or one of the other big ways to access the scientific data. If someone is offering a breast cancer treatment to re-regulate your micro-rna's, call your district attorney. Glad you have an inquiring mind and i wish you luck with your project.

Question 7

is plain chicken breast, asparagus, broccoli & cauliflower, mushrooms, and sweet potato a human healthy dinner?

Accepted Answer

Amount just as: Important. All of the foods you described are healthy but if you do not control the amount, even healthy foods will cause obesity and related problems.

Question 8

got raw packed chicken breast from bjs. wife wanted me to cut it in pieces never done it before. while cutting saw few dark brown blood on meat which i touched with fingers. most likely chicken blood. any hiv or hep risk if possibly human blood?

Accepted Answer

Do not fret: Even grocery store cooked chicken can have flecks of blood.  Just make sure it is fully cooked prior to eating.  Bigger risk is Salmonella, not HIV or HEP C.

Question 9

its said hiv virus is spread via blood, semen and vaginal fluid. is hiv virus present in other bodily fluids such as breast milk and human sweat?

Accepted Answer

Breast milk: Yes: The following fluids can contain high levels of HIV:
Blood, semen (cum), pre-seminal fluid (pre-cum), 
vaginal fluids, rectal (anal) mucus, and BREAST MILK and can infect.

Other body fluids and waste products—like feces, nasal fluid, saliva, SWEAT, tears, urine, or vomit—DO NOT contain enough HIV to infect.

Question 10

if doctors don't know what is going on in my breast and biopsy came out cell reaction and just did mammo&ultrasound still adnormal would do a part mast?

Accepted Answer

Get 2nd opinion: I do not ordinarily express lack of confidence in colleagues, but your story is disturbing enough for me to urge a serious consult. There may be a misunderstanding ("reaction" implies not cancer and a "partial mastectomy" does not sound appropriate.) but it's clear your concerns are very real. Do not sign any consent until it's clear to you what's going on. Autonomy rules. Best wishes.
