Metrics details. A human breast has many lobes, which are highly variable in size and shape, each with one central duct, its peripheral branches and their associated glandular tissues. Realising the potential of new endoductal approaches to breast diagnosis and improving our understanding of breast cancer precursors will require greatly improved knowledge of this ductal-lobar anatomy and the distribution of cancer precursors within it. This architecture is very challenging to study in its entirety: whole-breast lobe mapping has only been achieved for two human breasts. Clearly, much more efficient techniques are required.

Secondary breast cancer in the lung

Breasts are made up of fat and breast tissue, along with nerves, veins, arteries and connective tissue that helps hold everything in place. The main chest muscle the pectoralis muscle is found between the breast and the ribs in the chest wall. Image source: National Cancer Institute www. Breast tissue is a complex network of lobules small round sacs that produce milk and ducts canals that carry milk from the lobules to the nipple openings during breastfeeding in a pattern that looks like bunches of grapes. During puberty, hormones produced by the ovaries and pituitary gland a part of the brain that controls growth and other glands in the body cause the breasts to grow. This causes the milk ducts to stretch out and become more branched.

Metrics details. Multiple primary malignant tumors MPMT refers to the presence of two or more primary cancers of different organs in the same patient. MPMT is a sparse disease in the past, but there has been a gradual increase in the morbidity. Since multiple primary malignant tumors treatment methods differ, it is essential for clinicians to be able to distinguish between separate primary lesions and metastasis. We present the case of a year-old woman with MPMT presenting with cancer in the left breast and synchronous double primary lung adenocarcinomas.
