All of the following are invasive carcinoma breast except
**Core Concept**
Invasive carcinoma of the breast refers to a type of cancer where malignant cells infiltrate through the basement membrane of the ductal or lobular epithelium and invade the surrounding breast tissue. This is in contrast to non-invasive or in situ carcinomas, which remain confined within the epithelial layer.
**Why the Correct Answer is Right**
Invasive carcinomas of the breast are characterized by their ability to invade surrounding tissues, including blood vessels and lymphatic channels, facilitating metastasis. The correct answer is an invasive carcinoma type that is recognized by its distinct histological features and clinical behavior. Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) are the most common types of invasive breast carcinomas.
**Why Each Wrong Option is Incorrect**
**Option A:**
This option is incorrect because invasive carcinoma types are typically characterized by their invasive growth pattern, whereas in situ carcinomas remain confined within the epithelial layer.
**Option B:**
This option is incorrect because it is a type of in situ carcinoma, which does not invade surrounding tissues.
**Option C:**
This option is incorrect because it is a type of in situ carcinoma, which does not invade surrounding tissues.
**Option D:**
This option is incorrect because it is a type of in situ carcinoma, which does not invade surrounding tissues.
**Clinical Pearl / High-Yield Fact**
The distinction between invasive and in situ carcinomas is crucial in breast cancer diagnosis and treatment, as invasive carcinomas require more aggressive therapy and have a higher risk of metastasis.
**Correct Answer: D. Ductal carcinoma in situ.**
