How does colloid carcinoma of the breast typically present in terms of aggressiveness?

Colloid carcinoma, also known as mucinous carcinoma, is a special type of breast cancer characterized by the presence of mucus-producing cancer cells. This carcinoma tends to be less aggressive compared to the more common forms such as invasive ductal carcinoma.

In general, colloid carcinoma is associated with a better prognosis, often presenting at an earlier stage and having a slower growth rate. Its unique histological features, particularly the predominant mucinous components, contribute to its less aggressive nature. Studies have shown that while it can metastasize, the frequency and aggressiveness of spread are not as pronounced as in other types of breast cancers.

The other answer choices suggest characteristics that are not typically associated with colloid carcinoma. For example, the idea that it is highly aggressive and metastatic does not align with clinical findings, which demonstrate a tendency towards lower metastatic potential. Furthermore, the expectation of it always presenting with lymphatic spread or being often fatal within a year contradicts the slower progression and more favorable outcomes usually seen with this type of cancer.
