Primary tumor is a tumor growing at the anatomical site where tumor progression began and proceeded to yield a cancerous mass. Metastasis(Pleural effusion) is excess fluid that accumulates in the pleural cavity, the fluid-filled space that surrounds the lungs. Cancer cells can break away, leak, or spill from a primary tumor, enter lymphatic and blood vessels, circulate through the bloodstream. Metastasis is one of three hallmarks of malignancy.
Fig. 2. Morphologies of breast cancer cell lines cultured in 2D and 3D. (Top) Images of 4 representative breast cancer cell lines cultured as 2D monolayer, (middle) and in 3D lrBM grouped by 3D morphological classification: Round, Mass, Grape-like and Stellate. (Bottom) 3D cultures were stained for F-actin and nuclei were counterstained with DAPI. Scale bars: top panel, 100$m; middle panel, 50$m; bottom panel, 20$m. Adapted from ref. [77].
