How Can I Determine If My Lumps Are Cancerous While Having Dyspnea, Dysphagia, Electric Shocks, And Lumps After Exposure To Hydrated Lime?

i have been diagnosed with dyspnea, dysphagia, and sleep somonlonce. I havei lumps that feel like tumors come up on my torso and my arms. NIne to be exact. i experience what feels like electric shocks often across my chest and between my ears. when i do fal asleep and wake up i experience where i cant catch my breath in my chest. i only had one lump. it was after i accidentally breathed in hydrated lime (calcium hydroxide) while dispresing it over an over flow of a septic system that i then gained the other 8 lumps. i often hear these sounds like voices that i know arent there. how can i find out if these lumps are cancer? i feel daily like i am sick and dying. what is your advice on the proper steps to get these symptoms diagnosed correctly? i seen an AR Care dr and asked him to schedule me an MRI and he said he would but it was after my insurance dened it i found out that the dr. put in his notes that he didnt feel like it was neded. i dont know what to do next. can you please give me the right words to say to a dr. to get me on the right path? it as if no one will listen to me.
