Whether pleurisy with effusion is easy to treat depends on identifying the cause of the pleurisy, which commonly includes tuberculosis, infection, and tumors.

Tuberculous pleurisy can usually be cured about six months to a year after standard anti-tuberculosis treatment; infectious pleurisy generally has a good prognosis if it is sensitive to anti-infective drugs; however, pleurisy caused by tumors often indicates metastasis to the pleura, and at this stage, surgical options are no longer viable, leading to a poor prognosis.

Therefore, if pleurisy is present, it is necessary to go to the hospital to complete thoracic puncture and clarify the nature of the pleural effusion, and treat according to the cause.
