Cancer is a collection of diseases in which aberrant cells grow uncontrolled and invade surrounding tissues. Cancer can be classified as carcinoma, sarcoma, leukemia, or lymphoma. The deadliest cancers are lung, breast, colorectal, pancreatic, and prostate. Chemotherapy, surgery, and radiotherapy are the usual cancer treatments. However, drug resistance poses a significant barrier to cancer treatment. Macroalgae are wellknown producers of bioactive compounds with antimicrobial, antioxidant, anti-inflammatory, and anti-cancer properties. Red algae, in particular, are a prominent source of bioactive substances, such as polysaccharides, phenolic compounds, lipids, sterols, alkaloids, and terpenoids. Therefore, molecules from marine resources could be an appealing way to identify new cancer treatment alternatives. This study aimed to provide a brief overview of what is currently known regarding the potential of red macroalgae in cancer treatment by discussing the primary therapeutic targets of the disease and identifying compounds or extracts with bioactive characteristics against them.
Keywords: Cancer; bioactive compounds; inflammatory; lipids; marine algae; red algae.
