Breast cancer is cancer that develops from breast tissue. Risk factors for developing breast cancer include being female, obesitylack of physical exercise, drinking alcoholhormone replacement therapy during menopauseionizing radiationearly age at first menstruationhaving children late or not at all, older age, prior history of breast cancer, and family history. The balance of benefits versus harms of breast cancer screening is controversial.
Invasive carcinoma of no special type NST also known as invasive ductal carcinoma or ductal NOS and previously known as invasive ductal carcinoma, not otherwise specified NOS is a group of breast cancers that do not have the "specific differentiating features". In this group are: pleomorphic carcinoma, carcinoma with osteoclast-like stromal giant cells, carcinoma with choriocarcinomatous features, and carcinoma with melanotic features. Invasive carcinoma of no special type NST is the most common form of invasive breast cancer.
There are many types of breast neoplasmswhich can be divided into the following broad oversimplified categories as a starting point. Intralobular and interlobular refer to the terminal duct lobular unit. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.
Professional coaching keeps doctors in the game. Atypical vascular lesions AVLs of the breast are rare cutaneous vascular proliferations that appear as flesh-colored or erythematous papules or macules in women who have undergone radiation treatment for breast carcinoma. These lesions can develop in the irradiated area up to 20 years after the radiation treatment but most commonly occur within 3 to 6 years. The general consensus agrees on the benign nature of AVLs; however, their identity as benign lesions has been a source of controversy over the years, with some investigators proposing that AVLs may be a precursor lesion to postirradiation angiosarcomas.
Not all breast cancers are the same. Understand what type of breast cancer you have and how it differs from other types of breast cancer. Once you've been diagnosed with breast cancer, your doctor will review your pathology report and the results of any imaging tests to understand the specifics of your tumor.
Non-cancerous and cancerous breast lumps can be very different from each other when it comes to how they feel during a breast exam and what they look like in imaging tests. However, a number of benign breast changes mimic breast cancerso it sometimes takes further testing to know for sure what's going on in your breast. How a breast mass feels can give a doctor a fairly good idea whether a lump is a breast cancer tumor or a benign mass.
Breast calcifications are small spots of calcium salts. They can occur anywhere in the breast tissue. Breast calcifications are very common and usually develop naturally as a woman ages. They are usually benign not cancer.
A lump in the breast is a cause of great concern. High frequency, high-resolution USG helps in its evaluation. This is exemplified in women with dense breast tissue where USG is useful in detecting small breast cancers that are not seen on mammography.
This study aims to evaluate whether the distribution of vessels inside and adjacent to tumor region at three-dimensional 3-D power Doppler ultrasonography US can be used for the differentiation of benign and malignant breast tumors. Blood vessels within and adjacent to tumor were estimated individually in 3-D power Doppler US images for differential diagnosis. Neural network was then used to classify tumors by using these vascular features.
