Current status on VA recognizing squamous cell carcinoma contracted from agent orange exposure

Vietnam era veteran stationed in Southeast Asia in early 1970s...worked on planes that dispersed agent orange....contracted stage 4 squamous cell carcinoma of the neck/throat in 2008....from that point of time in my life, it all went downhill fast. Diagnosed with Stage 4 lung cancer in 2009 and 2011 I've also had Stage 3, melanoma/basal cell sarcoma of the nose. I have hypertension, hyperthyroidism, stent in my coraitid artery, stents in my heart arteries, etc, etc.,..ugh. VA gave me a 30% disability rating for my heart condition only...after i applied through the Pac/Act of 2022. Why only that %?....what about all the cancers I've had., amongst other things...I'm at a loss on how to fight these guys. Can someone please offer me some status updates on this form of unrecognized cancer and what I need to do to get what's owed for all my pain and medical suffering?
