What started out as a routine heart scan turned into another scan because they noticed a mass on my right hilum it's further shown another mass on my lungs so two masses in total with swollen clavicle lymph nodes and swollen neck lymph nodes I'm due to have a biopsy in January I'm really really scared as it's only under sedation to confirm lymphoma. 

I'm only 38 with four kids and a partner who's lost his mum dad and twin brother in the last five years

I'm shocked scared angry and just feeling really sad. Is this normal. The procedure sounds quite scary and due to my heart problems I'm scared I'm going to die.
