Do TB skin tests leave scars for lifetime or they disappear aftr some time? Do they disappear only for negative cases or disappr in positive cases too

Do TB skin tests leave scars for lifetime or they disappear aftr some time? Do they disappear only for negative cases or disappr in positive cases too

Usually TB tests: Do not leave scars however a rare highly positive test can lead to minor skin damage and a "reminder" (scar) never to have another TB test again!!!
(The first "positive" especially the "severe" ones should result in TREATMENT with anti-TB medication (INH)

Hope this helps!

Mycobacterium tuberculosis is an infectious organism that spreads by droplets coughed out by an infected person. Infection is established initially in lungs, but can spread within lungs & to other body parts, or can become latent, with reactivation occurring years to decades later. With effective treatment, it can be completely eliminated although drug resistant ...Read more

Tb scars are something to worry about? Shall I get married? After PTB with scars what is life? Can TB scars cause breathing prblmes or pain?

Tb scars are something to worry about? Shall I get married? After PTB with scars what is life? Can TB scars cause breathing prblmes or pain?

Tuberculosis: Pulmonary scarring from tuberculosis may not produce significant problems, but this depends upon how extensive and where the scars were located. In any event this should not influence whether you date or get married. If he loves you, none of this will matter, and the overwhelming probability is that you will be just fine. Best wishes. ...Read more

Doc how can you determine if the nodular density is the active TB or a scar? Thank you doc.

Doc how can you determine if the nodular density is the active TB or a scar? Thank you doc.

TB vs scar: Nodular densities in the lung are often seen as a result of scarring. If you are concerned about TB then getting a TB skin test would be the first step. If it is negative then the nodule in the lung is not TB. If it is positive and you are not coughing then it means you have been exposed to TB but do not have active TB. If it is positive and you are coughing then you need sputum culture done. ...Read more

I had TB 6 years ago, and made a scar on my right upper lung. Is there a possibility that it will be rem0ved?

No: The right upper lobe does not participate much in overall function of the lung. A scar in this area is usually well tolerated and doesn't cause any symptoms. Sometimes though a fungal infection can occur in the location of a prior TB scar. ...Read more

Can old TB scars remain permanently? And it will be visible on routine chest xrays? Please I need a answer. Doctor please reply me please

Scars on xray: Scarring may get smaller but will not go away completely. Whether this can be seen on routine chest xray depends on the size. As long as it does not get bigger on xray there is no cause for concern. ...Read more

Can TB scars cause any problems? Is scar cancer possible? Can I get married after treatment? Can I eat frozen icecreams etc aftr treatment? Plz rply.

Good news: I think I already answered you about the cancer risk from the scar being trivial, extremely low. Of course you can get married -- it's your choice, just like ice cream. Your physician will be a good guide for you. Especially, be grateful that TB is being cured nowadays thanks to real science, and stop reading internet scare stories. ...Read more

I had TB as a kid and that resulted in a big scar on my face. Now I have 1 red pimple. Is this a symptom of tb? Am I going to have 1 more scar on face?

Best to see a doctor: This type of question cannot be answered without more information, a physical exam and perhaps a few lab tests. Tb is a serious illness that should be treated promptly. See you physician to see if TB is the problem, or if it is something else. ...Read more

Chest x-ray showed fibronodular opacities in right upper & left mid zone. Had TB 4 yrs back, are these scars from earlier tb? Can this be removed?

This is a Complex Qu: This is a complex issue. Yes, TB can and often does cause fibrosis/nodular changes which typically regress partially or complete once a full course of treatment has been taken. There is of course risk of recurrence of TB. So we have to find out if your lung changes are left over of the older TB or are these new changes (progression). For this you need to go back to the doctor who treated your TB. ...Read more

How can old TB scars cause lung cancer in non smoker?

How can old TB scars cause lung cancer in non smoker?

They do not but: Cancer develops when immunity surveillance decreases by age, infections and genetic alterations.....
Etiology of lung cancer in non- smokers is unclear but genetic alteration is largely to blame. Air pollution and second- and third- hand smoking could play a part. Tb scar in the lung could be a milieu or area for developing cancer to nest in....But, this is very rare. Thank you. ...Read more

Can a previous TB scar cause lung cancer even if non-smoker?

Can a previous TB scar cause lung cancer even if non-smoker?

Cannot say no: While there have been studies associating an increased risk of certain lung cancers in people with a history of tuberculosis, there is no proof that the infection causes cancer. Correlation is not the same as causation. So I can't say no, but I can't say yes either! ...Read more

Does pulmonary TB scars cause shortness of breath during sex?

Does pulmonary TB scars cause shortness of breath during sex?

Tuberculosis: This obviously depends upon the extent of the scarring. If it is severe enough to cause shortness of breath with exertion this would not be confined to sexual activity, but to any form of extreme exercise. It would be unusual in the USA to see pulmonary scarring of that extent, assuming the TB had been recognized and treated appropriately. ...Read more

From my CT scan, what is nodular parenchymal opacity (1.5 mm)? Does it indicate an old TB scar? X ray looks fine

From my CT scan, what is nodular parenchymal opacity (1.5 mm)? Does it indicate an old TB scar? X ray looks fine

Check it out: Xrays look at differences in density. Chest xrays take 2 views while a ct takes a 360 degree view and is more sensitive. You have a small nodular (round) opacity (denser than the surrounding lung) that only is visible on ct. Xrays take pictures and may not not provide a specific diagnosis. The nodule may represent old TB but you need a doctor and possibly other tests to decide this. ...Read more

What is the life expectancy with pulmonary TB scars? Shall I get married? Will the fibrotic element in my upper lung due to TB cause prblems in future

Enjoy life: Always have a good primary care doctor, and always buy good, non-hmo insurance so that doctors have plenty of time to take care of you. See the doctor for ill symptoms and for regular check-ups. Other than that, one can live life as if there were no TB lung scars, after finishing treatment. That means go out, meet people, get married, have children and grandchildren, and live happily ever after. ...Read more

Hi doctor, m cured frm TB bt TB left scars. Can I get lung cancer/any other disease bcz of TB scars? 22 year old female. I don't smoke. Plz reply me.

Don't worry: We've both been cured of TB and that's a good thing. The tiny statistical cancer risk that these old scars pose (and not everybody believe they even do) isn't something we can do anything about. You can't remove the scar, and nowadays it's not considered even worth getting radiation to look for it. Just be grateful that TB is now manageable. Best wishes. ...Read more

After TB lymphadentitis treatment is there a possibility to get a lung scar without having pulmonary tb? Chest glands were enlarged.

After TB lymphadentitis treatment is there a possibility to get a lung scar without having pulmonary tb? Chest glands were enlarged.

Lung Scars: Tuberculosis infections can certainly cause (calcified scars) or granulomas.
Such scars can also be caused by previous lung infections such as pneumonia, certain fungus in the soil known as histoplasmosis which sometimes causes infection but rarely causes any health problems. After receiving adequate treatment for TB lymphadinitis, a watchful waiting would be advised. ...Read more
