How long can you live without spleen? Higher chance of cancer or serious life issues? Had a splenectomy. Am 20 years old want to live to 80

Having no spleen. is not uncommon, many people don't, either born without, lose it to a disease or trauma ,get it urgically removed,or due to other conditions,vaccines against pneumococcus,meningitis and h. Flu should be administered, others like flu shots every year would be needed, antibiotics should be started as soon as infection is suspected, keep antibiotics handy when you travel, follow up with doctor often,
