Can you have lung cancer without symptoms?

Ty, You may have to work very hard for this love of yours.
Cancer is one of those struggles that science is making amazing progress with. https://www.uchicagomedicine.org/forefront/cancer-articles/clinical-trial-helps-patient-with-stage-4-lung-cancer
I hope the biopsy is clear. Adding my prayers to yours.

I am so very sorry you are going through this. Fear is a normal response in this situation. For me , my faith is what helped me to deal with cancer and fear the most.
Do you have a faith foundation you can lean on? You said this was his second time? What helped you thru the first experience?
Sometimes having someone to talk to is helpful. A pastor, or therapist, even a trusted friend . Most hospitals have a Chaplain service that can offer some specialized supports or referrals to support groups etc. Chaplains are familiar with supporting individuals in crisis. I know this is a time of crisis for you.
You will also get lots of support and input from this group.
In my thoughts and prayers Chaplain Lynne

@scared2 , Cancer is scary. Having the results from the biopsy will give you and his doctors the information that they need to determine the next steps, toward treatment. Some cancers in the lung are metastatic from other areas, or they are a primarily lung cancer. Even within the diagnosis of lung cancer, there are many different types. Each type has its own approach to treatment.
Hearing 'stage IV' is life changing. Keep in mind that treatments today are better than ever, and there is finally real hope in the lung cancer realm. I was diagnosed with stage IV lung cancer five years ago, and I'm doing well on treatment. I deal with medication side effects, but most people would not know I have stage IV cancer.
Our lungs don't have pain sensors, so you don't feel them when you breath. Unfortunately, many lung cancers are diagnosed at advanced stages, especially in patients that don't qualify for screening.
Try to focus on what's right in front of you. Has the biopsy been scheduled yet?

One reason lung cancer has been so hard to fight is that there is no early detection method as simple as a mammogram or the PSA for prostate. Often there are no symptoms until it metastasized to another organ.

Mine was not found till stage 4. That was 2010, so 14+ years ago.

This is for a list of questions to ask the oncologist about dealing with lung cancer from diagnosis to survivorship. It's on the American Cancer Society Website.
