Brazil highlights less‑invasive head‑and‑neck cancer treatments during July awareness

July is observed in Brazil as "Green July," a month dedicated to raising awareness of head‑and‑neck cancer, which includes tumours of the mouth, throat, larynx, nasal cavity and salivary glands. Specialists note that many cases are diagnosed at advanced stages – about 80 % in stages III or IV – making early detection crucial.

Interventional radiology is being promoted as a less‑invasive way to manage complications such as bleeding, infections and vascular issues. Dr. Guilherme Martins, a radiologist, explains that image‑guided biopsies, embolisation of hemorrhages, drainage of infections and placement of venous access can be performed through small vascular accesses, helping patients continue their cancer therapy safely.

Risk factors highlighted include tobacco use, excessive alcohol consumption and HPV infection. New therapeutic options, such as the immunotherapy drug pembrolizumab approved by ANVISA for high‑risk cases, are also expanding treatment possibilities. Experts stress that prevention, vaccination and prompt medical evaluation of persistent symptoms remain the most effective strategies.
