'Genesung' (recovery) is derived from the verb 'genesen' (to recover), which means 'gesund werden' (to get well). The ending '-ung' turns the verb into a noun, which is always feminine (die Genesung).
Der Patient ist nach der Operation schnell wieder genesen.
The patient recovered quickly after the operation.
The word is very often used in fixed expressions. Typical ones are 'gute/schnelle Genesung wünschen' (to wish someone a good/speedy recovery), 'auf dem Weg der Genesung sein' (to be on the road to recovery), and 'die Genesung unterstützen' (to support recovery).
Eine gesunde Ernährung kann die Genesung nach einer Krankheit unterstützen.
A healthy diet can support recovery after an illness.
'Genesung' (recovery) is a rather formal word that is often found in written language, in hospitals, or on greeting cards. It sounds more formal and medical.
Der Arzt war mit dem Fortschritt der Genesung sehr zufrieden.
The doctor was very satisfied with the progress of the recovery.
illness
'die Erkrankung' and 'die Genesung' stand in clear contrast. 'Erkrankung' describes someone becoming ill or being ill. 'Genesung' describes the path back to health after an illness, injury, or operation. The words often fit into the same medical context, but they show different phases: first the illness, then hopefully the recovery.

Nach der Operation braucht die Genesung viel Ruhe und Geduld.
After the operation, recovery requires a lot of rest and patience.
Während der Erkrankung konnte er nicht zur Arbeit gehen.
During the illness, he could not go to work.
