It is a noncancerous tumor mainly found in the breast of the women aged under 30.
They are composed mainly of stromal and epithelial tissues.
We all know that breasts are made up of milk producing glands known as lobules and ducts. All this arrangements are surrounded by some fatty tissues.
Fibroadenoma started to develop from the lobules and ducts and spread all over it to form a solid structure commonly known as lump. The lumps often highly mobile in the breast. This is the main difference with breast cancer.
It occurs mainly due to the hormonal imbalance. Estrogen may responsible for this type of noncancerous growth. This can grow during the time of pregnancy and menopause.

We all know our cell membrane possesses different types of protein some of them are peripheral and others are integral. Aquaporin are integral proteins found in the cells which help to transport water from one cell to another. According to their function they are named as water channel . Just take a look at their name Aquaporin , here Aqua means water and porin means pore or channel. So it is clear from there name, that they form pores on the surface of biological membranes, and mainly water transports through it. This channels are composed mainly of six transmembrane Alpha helices. As they are integral proteins so they embedded in the cell membrane, the amino and carboxyl ends face the inside half of the cell. Aquaporin creats four part clusters in the cell membrane, they are the monomers and all of them serves as water channel. In mammals there are 13 known types are present ,it is astonishing that among them 6 are present in kidney ...
