How long does it take for breast cancer to mestesise to the retina?

Rarely: While breast cancer can metastasize, it is rare for it to go to the retina. The time until a breast cancer spreads depends upon the aggressiveness of the cancer, not the site to which it travels.

Breast cancer: That is a very unusual place for breast cancer to spread to. In general if breast cancer spreads, the most common organs it spreads to are the lungs, liver, bones, and brain. This can occur at any time around the diagnosis of the breast cancer, but is mostly likely within the first 2 years.

Well described: While the most common places for breast cancer to spread to are the lung, bones, brain, and adrenal glands, the most likely source or a metastatic tumor to the retina is from breast. How long it takes for it to spread and go there from the time it first develops is hard to determine since it depends in many variables related to the primary tumor.
