Can radiation therapy cause lung nodules?
Radiation pneumonitis can also manifest as nodular and focal consolidative opacities within the treatment port (,,,,Fig 3) (,28,,29). Although radiation pneumonitis usually occurs within the irradiated lung, radiation pneumonitis outside the treatment portals has been reported (,11–,13,,15,,30–,32).
What can cause lung nodules to grow?
What causes lung nodules? When an infection or illness inflames lung tissue, a small clump of cells (granuloma) can form. Over time, a granuloma can calcify or harden in the lung, causing a noncancerous lung nodule. A neoplasm is an abnormal growth of cells in the lung.
How fast do lung nodules grow if cancerous?
Growth: Cancerous lung nodules tend to grow fairly rapidly with an average doubling time of about four months, while benign nodules tend to remain the same size over time.

What is considered rapid growth for a lung nodule?
The Mechanics of Pulmonary Nodules There is very little growth or change, if there's any at all. Cancerous pulmonary nodules, however, are known to grow relatively quickly—usually doubling in size every four months but sometimes as fast as every 25 days.
What is the most common cause of multiple nodules in lung?
Multiple nodules in the lungs or multiple pulmonary nodules (MPN) refer to two or more lesions in the lungs. Lung cancer such as bronchoalveolar carcinoma and lymphoma are the most common causes of MPN. These infections result in inflammation, which further forms a granuloma.
Is a 4 mm lung nodule serious?
In general, nodules that are less than 6 mm (1/4 inch) in diameter are followed with a repeat chest CT scan due to the low risk of cancer (ten percent or less), unless some other feature is felt to increase the probability of cancer. Nodules between 6 mm and 10 mm need to be carefully assessed.
Should I worry about a 9mm lung nodule?
A nodule is generally considered small if it is less than 9 mm in diameter. Should I worry that I have a small nodule? Usually a small nodule (less than 9 mm) is not a cancer, but it still could be an early cancer.

What is a granuloma in the lung?
When an infection or illness inflames lung tissue, a small clump of cells (granuloma) can form. Over time, a granuloma can calcify or harden in the lung, causing a noncancerous lung nodule. A neoplasm is an abnormal growth of cells in the lung. Neurofibromas are a type of noncancerous neoplasm.
What percentage of lung nodules are benign?
About 95% of lung nodules are benign. Many things can cause benign lung nodules, including infections and scarring. If you have a pulmonary nodule, your healthcare provider may want to perform additional tests to determine the cause and rule out lung cancer.
How long does it take for a lung nodule to show up on a CT scan?
The findings are often a surprise. If an imaging test shows a lung nodule, your healthcare provider may recommend active surveillance. In six to 12 months, you get another CT scan. Nodules that stay the same size during a two-year surveillance period are not likely to be cancer.
What is CT scan for lung nodules?
CT scan-guided biopsy: For nodules on the outer part of the lung, your provider uses CT images to guide a thin needle through the skin and into the lung. This needle biopsy takes tissue samples from the nodule to examine for abnormal cells.
How long does it take for lung cancer to heal after radiation?
Most can be expected to improve within a few weeks after radiation therapy is completed.

What does a radiation oncologist do?
As part of the planning process for your therapy, your radiation oncologist will explain what you can expect and recommend ways to prevent or alleviate any associated discomfort. Your experience will be influenced by a variety of unique factors, such as the location and type of your tumor, your radiation dosage, your general health and any other treatments you may be receiving, such as chemotherapy.
Can radiation therapy cause cancer?
However, like many other treatments, it can cause certain side effects. Specifically, when healthy cells are exposed to radiation, they can be damaged in the same way that cancerous cells are, leading to adverse effects at the site of exposure. Because radiation therapy is a localized treatment, most side effects develop in the treatment area ...

Why is lung nodule growth important?
Lung Nodule Growth Rate: An Important Factor in Assessing Risk of Cancer. A cancer has to grow faster than the tissue around it to become a tumor. Progressive growth is therefore a central feature of a cancer and a critical factor in distinguishing cancerous nodules from benign ones.
What is the VDT of a nodule?
There is a characteristic "volume doubling time" (VDT), the interval it takes for a nodule to double in volume. It's worth keeping in mind that because a nodule is generally spherical, an increase in the diameter by just 28% (such as a 2 mm increase from 7 to 9 mm) actually represents a doubling of the volume of a nodule.
What is stability in cancer?
The common definition of stability is a lack of change over two years of observation, and then patients with a nodule being followed are generally felt to have a very low likelihood of cancer. However, I've seen a few cancers that didn't have convincing growth until more than two years of follow-up had been completed ...
Can cancer grow during observation?
And there's always a rare very rapidly growing cancer that can grow remarkably during a period of observation . The key is weighing the risk of watching (which usually helps to clarify the risk that a nodule really is cancer or not) vs. the risk of jumping in and overtreating lots of nodules that aren't cancer after all.
Does lung cancer grow faster on CT?
The calculator is here (and there's also some more information on imaging of lung cancer). The key points, though, are that cancers should grow over time of being observed on CT, and while there is a lot of variability in how quickly lung cancers grow, the fastest and slowest moving are less likely to be cancer than the ones ...

How do you know if you have radiation pneumonitis?
The main symptoms of radiation pneumonitis include: shortness of breath. dry cough. feeling of fullness in your chest. flu-like symptoms. These symptoms are very similar to those of both pneumonia and lung cancer. In addition, radiation therapy can cause similar side effects, even in people who don’t develop radiation pneumonitis.
How long does it take for radiation to clear up?
Treatment for radiation pneumonitis depends on how severe the condition is. For most people, symptoms clear up on their own within 7 to 10 days of appearing. However, more severe cases require aggressive treatment. The most common treatment for severe pneumonitis is a long course of corticosteroids, such as prednisone.
How to help a swollen throat?

Is radiation pneumonitis more likely to develop after radiation treatment?
Are there any risk factors? Some people are more likely than others to develop radiation pneumonitis after radiation treatment. The biggest factor involves the size of the area receiving radiation treatment. The larger the area, the higher the risk of developing radiation pneumonitis.
What is lung cancer recurrence?
There are three types of cancer recurrence: Local: The cancer has come back to your lungs. Regional: The cancer is in the lymph nodes near the lungs. Distant: The cancer is in another part of the body, like the liver, bone, or brain. Even though it’s in a different area, it’s still called a lung cancer recurrence.
What to do if you have lung cancer?

What is the most common type of lung cancer?
There are two types of lung cancer: Non-small-cell lung cancer (NSCLC) is the most common, accounting for roughly 85% of cases. The other kind is small-cell lung cancer (SCLC). If you have NSCLC, your chance of a recurrence depends on what stage you have. Your doctor will tell you your stage from 0 to IV.
What is it called when cancer spreads to lymph nodes?
If the cancer has spread to both lungs, lymph nodes, or to other parts of your body, that’s called the extensive stage. Treatment. Your doctors may recommend a different treatment for your cancer recurrence than what you did the first time. They will decide based on: Where it came back.
How does radiation help the immune system?
These drugs help your immune system fight cancer. Radiation therapy: High doses of radiation, such as X-rays, kill cancer cells or keep them from growing. This therapy can treat lung cancer that has spread to the bones or brain. It’s also used to relieve cancer symptoms.
How to cure cancer in the airways?
This can lead to breathing issues, like coughing and pain. You may need a treatment to clear things up. You could have laser therapy, which uses a laser to kill cancer cells. Another option is putting in a stent, a device that helps keep your airways open.
Types of Radiation Therapy
To understand success rates when treating lung cancer with radiation therapy, it's important to look at the different methods/types of radiation and the goals of treatment. Radiation therapy has changed considerably in recent years and has become much more effective and precise (fewer side effects) than in the past.
Small Cell Lung Cancer (SCLC) Success Rate
Small cell lung cancer accounts for roughly 13% of lung cancers and tends to spread early (often to the brain) and aggressively. 10 Roughly one-third of these cancers are diagnosed when they are considered "limited stage" tumors, and two-thirds are already extensive at the time of diagnosis. 11
Non-Small Cell Lung Cancer (NSCLC) Success Rate
The effects of treatments for non-small cell lung cancer are reported in different ways. In some cases, these are divided by the four stages of the disease. In others, they are roughly broken down into three stages: local tumors (stage 1 and some stage 2 tumors), regional (some stage 2 and some stage 3 tumors), and distant (stage 4 lung cancer).
Influencing Factors
There are a number of factors that can influence the success rate of radiation therapy, and it's important to keep these in mind when looking at general statistics that compare people as a whole.
Side Effects
As with any cancer treatment, radiation therapy can have side effects and adverse reactions at times. Some of these include:
Talk to Your Healthcare Provider
There is a lot of information to digest simply looking at the role of radiation therapy in the different types and stages of lung cancer, but individual differences are crucial as well. Every person is unique, and every lung cancer is different in some way.
Summary
Radiation therapy may be used for nearly any type or stage of lung cancer, but treatment goals differ. In early-stage lung cancer, radiation may be used in an attempt to cure the cancer. In this case, specialized radiation called stereotactic body radiotherapy (SBRT) may be as effective as surgery in some settings.

Hello porcelana, Welcome to Grace. I hope this is just a quick stop to find you don't have cancer. Remember this isn't cancer until there are cancer cells under the microscope. That's because it so often happens that everyone thinks something is cancer and all the tests point to cancer but it ends up not cancer. So hopes are for not cancer.

Janine really covered the issues well. I'll just add a few of my own thoughts, largely reiterating the issues.
Reply To: Lung nodule growing
Well, that delay makes sense -- it's just the reality of the system. Fortunately, if there is anyone in whom a delay is unlikely to make a significant difference in the prognosis, it's someone with a slow-growing, still small, and PET-negative lesion (presuming it's even cancer).
Reply To: Lung nodule growing
Ana, It sounds as if you're in good hands and have a good plan for a cure. I'm sure your body will let you know when it's time to work out again and how much. Be careful about the contact end of things. One thought I had was to ask about (and look up info on) respiratory therapy after surgery.
Reply To: Lung nodule growing
if there was such a thing I'd say, he sounds perfect. I know you asked for a doctor's reply and your get one. It's the beauty of Grace. I found Grace when I was looking for info and didn't even see or want to look at a forum; until I realized oncologists answered or made sure all answers were appropriate.
What happens to a tumor after radiation?
As the tumor cells die and break up, the body's white cells clear the debris and cause an inflammatory process, like a bruise. This inflammatory reaction can make the mass look larger, but this does not necessarily reflect tumor response or growth.
What happens if a cancer cell doesn't divide?
This is a complex question. The first point to be made here is that, with the exception of spermatozoa and lymphocytes (among the two most rapidly dividing cells in the body), cancer cells die what is called a mitotic death. This means that the cell dies when it attempts to divide. So, if a cell does not divide, then it does not die, but just sits there. At the same time, if a cell doesn't divide, it also cannot grow and spread.
How long does it take for a tumor to go away on a CT scan?
These inflammatory reactions usually subside over time, but it may take a few months to see this on CT scan or even up to a year on MRI. PET scans can indicate tumor activity, but can also show inflammation, so are also not generally accurate in areas treated with radiotherapy until several months have passed.
Can tumors shrink quickly?
In summary, some types of tumor cells shrink very quickly, and this shrinkage can be seen on a radiology scan. Even if no shrinkage is seen right away, cells may still be dying in response to radiation, sometimes causing an inflammatory response that can even make a mass look larger!
