Breast cancer
True or False: Lymphatic drainage patterns can vary significantly among individuals.
True
What is the role of sentinel lymph nodes in breast cancer?

True
Fill in the blank: The lymphatic vessels of the breast converge into the __________ lymphatic trunk.
subclavian
What anatomical feature helps in the drainage of the breast?
Cooper’s ligaments
Multiple choice: What is the most common site for lymphatic metastasis from breast cancer? A) Liver B) Bone C) Lungs D) Axillary lymph nodes
D) Axillary lymph nodes

False
Fill in the blank: The __________ lymph nodes are located along the internal mammary artery and drain the medial breast.
internal mammary
What is the significance of the axillary tail in lymphatic drainage?
It is a region where breast tissue extends into the axilla, influencing drainage patterns.
