It is possible for invasive lung adenocarcinoma to heal spontaneously. In fact, clinical data show that there are indeed cancers that may regress spontaneously, but the probability is very low, about 1 in 100,000, that is, only one out of 100,000 cancer patients may experience spontaneous disappearance of the tumor, which is very rare. So basically, in clinical treatment, it cannot be considered as a routine, but can only be described as an exceptional case, the reason for which is not fully understood now, and is only considered to be explained by the correction of the human immune system. More and more often, it is reported that the cancer heals itself, but the biggest possibility is that it is misdiagnosed and it is not an adenocarcinoma, and there is also a case that it does not really heal completely, but the diagnosis is healing.
